Version 0.4.2 - January 2018


We will be installing Metron 0.4.1 with HDP 2.5 on CentOS 7. We will also install MariaDB as a database for Metron REST. Additionally, we'll also install Apache NiFi.
I installed Metron in a test environment with 4 VMs to try it out as well as a single node. I'll try to write this guide so that the necessary steps can easily be adapted for other environments.


  • Single node: 8 CPUs, 32GB RAM.
  • Multiple nodes:
  • 4 VMs, 4 CPUs per VM and 16 GB RAM per VM.
  • Hosts: node1 node2 node3 node4


  • CentOS 7
  • Add the epel repository and update your system:

    yum install epel-release -y
    yum update -y
  • Set up passwordless SSH between our nodes. If passwordless ssh has not yet been set up within the cluster, then in main node generate key:

    cat /dev/zero | ssh-keygen -q -N "" 2>/dev/null
    cat .ssh/id_rsa.pub >> .ssh/authorized_keys
    chmod 400 .ssh/authorized_keys

    If you're not installing on a single node, add this newly generated key to all the slave nodes:

    ssh-copy-id -i ~/.ssh/id_rsa.pub <replace_with_node_ip>

Side note: You might have to adapt your sshd_config file and add "PermitRootLogin yes" amongst other parameters if you want passwordless root access, but that's outside the scope of this document.

  • Increase limits for ElasticSearch and Storm on nodes where you will be installing them (if you don't know, increase it everywhere):

    echo -e "elasticsearch - memlock unlimited\nstorm - nproc 257597" >> /etc/security/limits.conf
  • Adjust limits to secure level (link)

    ulimit -n 32768
    ulimit -u 65536
    echo -e "* - nofile 32768\n* - nproc 65536" >> /etc/security/limits.conf
  • Disable IPv6, leaving it enabled may force service to bind to IPv6 addresses only and thus resulting in inability to connect to it (source link):

    sysctl -w net.ipv6.conf.all.disable_ipv6=1
    sysctl -w net.ipv6.conf.default.disable_ipv6=1
    echo -e "\n# Disable IPv6\nnet.ipv6.conf.all.disable_ipv6 = 1\nnet.ipv6.conf.default.disable_ipv6 = 1" >> /etc/sysctl.conf
  • Disable Transparent Hugepage. Add "transparent_hugepage=never" to the end of the kernel line in "/etc/default/grub" and reboot. (Ambari demands it, do we need to comply?)

    # Change the line:
    GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet"
    # To:
    GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet transparent_hugepage=never"
    # Afterwards, run:
    grub2-mkconfig -o /boot/grub2/grub.cfg

    After reboot check that changes were applied (make sure that word "never" is selected in square-brackets):

    cat /sys/kernel/mm/transparent_hugepage/enabled
    always madvise [never]

    Alternatively, if you do not want to mess with kernel parameters, you can create a new systemd service which disables this on each boot. Create the file "/etc/systemd/system/disable-thp.service" with the following content:

    Description=Disable Transparent Huge Pages (THP)
    ExecStart=/bin/sh -c "echo 'never' > /sys/kernel/mm/transparent_hugepage/enabled && echo 'never' > /sys/kernel/mm/transparent_hugepage/defrag"

    Restart systemd, start the new service and make sure the new service runs at startup:

    # systemctl daemon-reload
    # systemctl start disable-thp
    # systemctl enable disable-thp
  • Disable SELinux (is a must to install Ambari and build Metron:

    setenforce 0
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

Metron install pre-preparation

  • On all nodes Install pre-requisites for Ambari:

    yum install git wget curl rpm tar unzip scp bzip2 wget createrepo yum-utils ntp python-pip psutils python-psutil ntp libffi-devel gcc openssl-devel -y
    pip install --upgrade pip
    pip install requests
  • On Metron node install java 1.8 (if you don't know which it is, install it everywhere):

    yum install java-1.8.0-openjdk java-1.8.0-openjdk-devel -y
  • Set path to Java 8 if it does not exist:

    export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")
  • Save export for future reboots:

    echo 'export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s_/jre/bin/java__")' > /etc/profile.d/java_18.sh
    chmod +x /etc/profile.d/java_18.sh
    source /etc/profile.d/java_18.sh
  • Download and install Maven 3.3.9:

    wget https://archive.apache.org/dist/maven/maven-3/3.3.9/binaries/apache-maven-3.3.9-bin.tar.gz
    tar -zxf apache-maven-3.3.9-bin.tar.gz
    mv apache-maven-3.3.9 /opt
    echo 'export PATH=/opt/apache-maven-3.3.9/bin:$PATH' > /etc/profile.d/maven.sh
    chmod +x /etc/profile.d/maven.sh
  • Check whether Maven works:

    source /etc/profile.d/maven.sh
    mvn -V

    You should see something similar to:

    # mvn -V

  • On Ambari node install and enable docker (we will need it to build Metron mpack for Ambari):

    yum install docker-io -y
    systemctl start docker
  • Also on your build box, install npm. This is needed to build metron-config, part of the UI.

    yum install npm -y
  • Add "    localhost" to /etc/hosts if it does not there already
  • Install the database we will use for Metron REST on Master node:

    yum install mariadb-server -y

    Install JAVA MySQL connector on all nodes:

    yum install mysql-connector-java -y

Configure database for Metron REST

If you haven't run `mysql_secure_installation` after the database installation, do that first:

systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb

Should produce following output:


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n]
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] n
 ... skipping.

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]
 ... Success!
By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]
 - Dropping test database...
ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist
 ... Failed!  Not critical, keep moving...
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]
 ... Success!

All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

Cleaning up...


Build Metron code

Now we are going to start building Metron code. For advanced users: there seems to be a new way of building mpack and rpms

  • Clone Metron repo and switch to 0.4.1 release:

    git clone https://github.com/apache/metron
    cd metron
    git checkout Metron_0.4.1
  • Build Metron with HDP 2.5 profile:

    cd metron
    mvn clean package -DskipTests -T 2C -P HDP-,mpack
    cd metron-deployment/packaging/docker/rpm-docker
    mvn clean install -DskipTests -PHDP-

If for some reason, the rpm-docker fails with the message "/bin/bash: ./build.sh: Permission denied", try disabling selinux:


setenforce 0


And run mvn commands again.

  • On all nodes, create a localrepo directory and copy the RPMs from Ambari node there:

    mkdir /localrepo
    cp -rp /root/metron/metron-deployment/packaging/docker/rpm-docker/RPMS/noarch/* /localrepo/
    createrepo /localrepo
  • If you're doing a multi node install, also copy the packages to the other nodes:

    ssh root@node2 mkdir /localrepo
    scp /localrepo/*rpm root@node2:/localrepo/
    ssh root@node2 createrepo /localrepo

    Make sure to do the above on each node.

  • Fetch & create logrotate script for Hadoop Services:

    wget -O /etc/logrotate.d/metron-ambari https://raw.githubusercontent.com/apache/metron/master/metron-deployment/roles/ambari_common/templates/metron-hadoop-logrotate.yml
    sed -i 's/^  {{ hadoop_logrotate_frequency }}.*$/  daily/' /etc/logrotate.d/metron-ambari
    sed -i 's/^  rotate {{ hadoop_logrotate_retention }}.*$/  rotate 30/' /etc/logrotate.d/metron-ambari
    chmod 0644 /etc/logrotate.d/metron-ambari

Ambari 2.4 with HDP 2.5 install

Inspired by: [https://docs.hortonworks.com/HDPDocuments/Ambari-]

  • Enable time sync, disable firewall and SElinux on every node (I know, but for the sake of simplicity, quickness & testing, I've disabled selinux):

    systemctl enable ntpd
    systemctl start ntpd
    iptables -P INPUT ACCEPT
    iptables -P FORWARD ACCEPT
    iptables -P OUTPUT ACCEPT
    iptables -t nat -F
    iptables -t mangle -F
    iptables -F
    iptables -X
    iptables-save > /etc/sysconfig/iptables
    systemctl stop firewalld
    systemctl disable firewalld
    setenforce 0 

    Also, if you are using CentOS 7 and Python 2.7.5 and above you will encounter an error during ambari agent install in Ambari UI:

    [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)

    To fix it disable cert check in Python like this (reference link):

    sed -i 's/verify=platform_default/verify=disable/' /etc/python/cert-verification.cfg
  • Make sure each node can resolve every other node's hostname or add hostname of each node to `/etc/hosts` on every node. For example add following lines in /etc/hosts of each node: node1 node2 node3 node4

    Where,, and are the IP addresses of your nodes and "node1", "node2", "node3" and "node4" are their respective hostnames.

  • On main node download and setup Ambari repo (you may replace the "" with a newer Ambari version number):

    wget -nv http://public-repo-1.hortonworks.com/ambari/centos7/2.x/updates/ -O /etc/yum.repos.d/ambari.repo
  • Check that it was added:

    yum repolist | grep ambari
    # Updates-ambari-   ambari- - Updates                             12
  • Install and setup Ambari server:

    yum install ambari-server -y
    ambari-server setup -s
  • Add Metron service to Ambari by running mpack command (make sure to specify correct path to mpack in --mpack=):

    ambari-server install-mpack --mpack=/root/metron/metron-deployment/packaging/ambari/metron-mpack/target/metron_mpack- --verbose
  • Start Ambari:

    ambari-server start
  • Access the Ambari UI by going to the following URL in a web browser: http://<replace_with_master_node_ip>:8080/. You can use admin/admin as username/password. Start the Install Wizard.

Get Started page: Enter any desired cluster name.

Select Version: Make sure "Public Repository" is checked. You should also see the /localrepo directory listed.

Install Options: Specify hostnames of your nodes where Ambari cluster should be installed (all the ones you have specified in /etc/hosts) in "Target Hosts". Copy content of the main node private key (/root/.ssh/id_rsa) in "Host Registration Information". If you receive the warning "The following hostnames are not valid FQDNs", ignore it and click OK.

Choose Services: Select following Services:

YARN + MapReduce2
Ambari Metrics



Zeppelin Notebook


Assign Masters: Assign "Kafka Broker" on all nodes. Make sure move following components on one common node (Taken from previous guide, is this still necessary?):

Storm UI Server
Metron Indexing
MySQL Server
Kibana Server
Elasticsearch Master
Metron Parsers
Metron Enrichment

Assign Slaves and Clients: select All for:


Customize Services: Following is a list of services that need to be configured:

  • Set the "NameNode Java heap size" (namenode_heapsize) from the default 1024 MB to at least 4096 MB under HDFS -> Configs.
  • For ElasticSearch:
    • Set "zen_discovery_ping_unicast_hosts" to the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.
    • Under "Advanced elastic-site": Change "network_host" to "". Do not do this if your Metron is exposed to the public internet! Is "[ _local_, _site_ ]" now.
  • Kibana:
    • Set "kibana_es_url" to http://<replace_with_elasticsearch_master_hostname>:9200. "replace_with_elasticsearch_master_hostname" is the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.
    • Change "kibana_default_application" to "dashboard/Metron-Dashboard"
  • Metron: Set "Elasticsearch Hosts" to the IP of the node where you assigned ElasticSearch Master on the Assign Master tab.
  • Storm: You might have to increase the number of "supervisor.slots.ports" from the default "[6700, 6701]" to "[6700, 6701, 6702, 6703, 6704]" if you're only installing a single node.
  • For metron REST use:
Metron JDBC client path: /usr/share/java/mysql-connector-java.jar
Metron JDBC Driver: com.mysql.jdbc.Driver
Metron JDBC password: <DB PASSWORD>
Metron JDBC platform: mysql
Metron JDBC URL: jdbc:mysql://<DB NAME>
Metron JDBC username: <DB USERNAME>
  • Set rest of the configuration values to recommended by Ambari or the ones you desire (like DB passwords) and perform install. In a 3 node cluster, I ended up with:

  • Install everything. Metron REST will probably not work as we still need to add a user and the database to MariaDB.
    At this point, make sure that all the services are up. You might have to manually start a few.
  • Configure a user for Metron REST in MySQL. On the node where you installed the Metron REST UI, do:
# mysql -u root -p

For example:

# mysql -u root -p
> CREATE USER 'metron'@'localhost' IDENTIFIED BY 'metron';
> GRANT ALL PRIVILEGES ON metronrest.* TO 'metron'@'localhost';
> quit
  • There's 1 last step we need to do before the metron REST service will run. Due to systemd in Centos 7, doing service metron-rest start <PASSWORD> no longer works. Instead we have to edit the configuration file "`/etc/rc.d/init.d/metron-rest`". In this file, change `METRON_JDBC_PASSWORD="$2"` to `METRON_JDBC_PASSWORD="<DB PASSWORD>"` and restart the metron-rest service via the Ambari interface. Make sure that the Metron REST UI is started when moving to the following item.
  • Add the Metron REST username and password to the metronrest database:
# mysql -u <DB USERNAME> -p
> use <DB NAME>;
> insert into users (username, password, enabled) values ('<USERNAME>','<PASSWORD>',1);
> insert into authorities (username, authority) values ('<USERNAME>', 'ROLE_USER');
> quit
  • For example, to use the username 'metron' with password 'metron', do the following:
# mysql -u metron -p
> use metronrest;
> insert into users (username, password, enabled) values ('metron','metron',1);
> insert into authorities (username, authority) values ('metron', 'ROLE_USER');
> quit

Make sure that all the services are up.

  • Install metron_pcapservice:

Miscellaneous Issues

  • I had a problem with Zeppelin after rebooting this machine and had to manually create the Zeppelin run directory:
# mkdir /var/run/zeppelin
# chown zeppelin.hadoop zeppelin/
  • Additionally, while working with Metron, I've noticed that at some point Zeppelin Notebook started, but immediately stopped again. In the logs, I could see "Address already in use" messages. It turns out that there was still a lingering Zeppelin process on the host. To fix it, stop Zeppelin Notebook in Ambari and then kill the latent process:
# ps aux | grep zeppelin
# kill <zeppelin_java_pid>

Afterwards, restart Zeppelin Notebook via Ambari.

  • I had a couple of issues with Elasticsearch where it wouldn't find a master. This was fixed by doing the following. In Ambari, set the following items:

"masters_also_are_datanodes" to "true"
"expected_data_nodes" = "0"
"gateway_recover_after_data_nodes" = "1"
Restart all services. At this point, I noticed the following in :/etc/elasticsearch/elasticsearch.yml":

  data: "true"
  master: "true"
  name: metron1.local

After changing this to :

  data: true
  master: true
  name: metron

and restarting elasticsearch with "service elasticsearch restart", elasticsearch started indexing.

  • Another issue with Elasticsearch was that I saw the following error message in Kibana:
plugin:elasticsearch     Elasticsearch is still initializing the kibana index.

This was fixed by deleting the Kibana index ".kibana": "curl -XDELETE http://localhost:9200/.kibana"

Miscellaneous Services


  • Load the correct Elasticsearch template with:
    "# curl -s -w "%{http_code}" -u <USERNAME>:<PASSWORD> -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install ES Template from REST", "command": "ELASTICSEARCH_TEMPLATE_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "<HOSTNAME>"}]}' http://<AMBARI HOST>:8080/api/v1/clusters/<CLUSTERNAME>/requests"

For example:

"# curl -s -w "%{http_code}" -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install ES Template from REST", "command": "ELASTICSEARCH_TEMPLATE_INSTALL"},"Requests/resource_filters": [{"service_name": "METRON","component_name": "METRON_INDEXING","hosts" : "metron"}]}'"

  • Load Kibana Dashboard with:

"# curl -s -w "%{http_code}" -u <USERNAME>:<PASSWORD> -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install Kibana Dashboard from REST", "command": "LOAD_TEMPLATE"},"Requests/resource_filters": [{"service_name": "KIBANA","component_name": "KIBANA_MASTER","hosts" : "<HOSTNAME>"}]}' http://<AMBARI HOST>:8080/api/v1/clusters/<CLUSTERNAME>/requests"

For example:

"# curl -s -w "%{http_code}" -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{ "RequestInfo": { "context": "Install Kibana Dashboard from REST", "command": "LOAD_TEMPLATE"},"Requests/resource_filters": [{"service_name": "KIBANA","component_name": "KIBANA_MASTER","hosts" : "metron"}]}'"

  • If you installed Metron on a single node, you might have to increase the number of Storm supervisor slots from the default 2 to 5 or more. This can be done by editing the "supervisor.slots.ports" under Storm in the Ambari UI.

Change: "supervisor.slots.ports: [6700, 6701]" to "supervisor.slots.ports: [6700, 6701, 6702, 6703, 6704, 6705]"

# cd /root
# wget http://apache.mirror.iweb.ca/nifi/1.2.0/nifi-1.2.0-bin.tar.gz
# tar xf nifi-1.2.0-bin.tar.gz

Before we run NiFi, we need to change the port as the default port collides with the Ambari port. To do this, we need to change the value "nifi.web.http.port=8080" to "nifi.web.http.port=8089" in the file "nifi-1.1.2/conf/nifi.properties". Install and start NiFi afterwards:

# nifi-1.2.0/bin/nifi.sh install
# nifi-1.2.0/bin/nifi.sh start
