Installing Sentry 

 

The new feature Sqoop integration will be release 1.6.0. Any user which wants to use this feature should build the Sentry package from trunk.

$ git clone https://github.com/apache/incubator-sentry.git 
$ mvn clean  install –DskipTests
$ cp sentry-dist/target/apache-sentry-1.6.0-incubating-SNAPSHOT-bin.tar.gz ${yourTestDir}
$ cd ${ yourTestDir}
$ tar –xzvf apache-sentry-1.6.0-incubating-SNAPSHOT-bin.tar.gz
$ cd apache-sentry-1.6.0-incubating-SNAPSHOT-bin
$ export SENTRY_HOME=`pwd`
$ export PATH=${PATH}:${SENTRY_HOME}/bin

Initializing database for Sentry Service 

 

The Sentry Service uses Database to store privilege metadatas. Sentry uses JDO layer to decouple the underlying specific database. So the Sentry supports a lot of Database type such as Mysql, Oracle, Postgres, DB2 and Derby. The user should at firstly initialize the Database schema before starting the Sentry Service. The Sentry has already supply the initializing tool for all kinds of Database.

 

 

Initialize Derby:

Prepare a configuration file sentry-site.xml before executing the initialize command.

The configuration must contain information about sentry.store.jdbc.url, sentry.store.jdbc.driver,  sentry.store.jdbc.user and sentry.store.jdbc.password.

 

The sentry-site.xml:

 

<configuration>
  <property>
    <name>sentry.store.jdbc.url</name>
    <value>jdbc:derby:;databaseName=sentry_db;create=true</value>
    <description>JDBC connection URL for the backed DB</description>
  </property>
  <property>
    <name>sentry.store.jdbc.user</name>
    <value>Sentry</value>
    <description>Userid for connecting to backend db </description>
  </property>
  <property>
    <name>sentry.store.jdbc.password</name>
    <value>Sentry</value>
    <description>Sentry password for backend JDBC user </description>
  </property>
  <property>
    <name>sentry.store.jdbc.driver</name>
    <value>org.apache.derby.jdbc.EmbeddedDriver</value>
    <description>Backend JDBC driver - org.apache.derby.jdbc.EmbeddedDriver (only when dbtype = derby) JDBC Driver class for the backed DB</description>
  </property>
</configuration>

 

$ sentry --command schema-tool -dbType derby -initSchema -conffile sentry-site.xml

 

Initialize Mysql:

 

The sentry-site.xml:

 

<configuration>
  <property>
    <name>sentry.store.jdbc.url</name>
    <value> jdbc:mysql://10.239.47.76:3306/sentry?useUnicode=true&amp;characterEncoding=UTF-8 </value>
    <description>JDBC connection URL for the backed DB</description>
  </property>
  <property>
    <name>sentry.store.jdbc.user</name>
    <value>root</value>
    <description>Userid for connecting to backend db </description>
  </property>
  <property>
    <name>sentry.store.jdbc.password</name>
    <value>password</value>
    <description>Sentry password for backend JDBC user </description>
  </property>
  <property>
    <name>sentry.store.jdbc.driver</name>
    <value> com.mysql.jdbc.Driver</value>
    <description>Backend JDBC driver - org.apache.derby.jdbc.EmbeddedDriver (only when dbtype = derby) JDBC Driver class for the backed DB</description>
  </property>
</configuration>

 

$ sentry --command schema-tool -dbType mysql -initSchema -conffile sentry-site.xml

 

Initialize Postgres:

 

The sentry-site.xml:

 

<configuration>
  <property>
    <name>sentry.store.jdbc.url</name>
    <value>jdbc:postgresql://server-582:5432/sentry</value>
    <description>JDBC connection URL for the backed DB</description>
  </property>
  <property>
    <name>sentry.store.jdbc.user</name>
    <value>sentry</value>
    <description>Userid for connecting to backend db </description>
  </property>
  <property>
    <name>sentry.store.jdbc.password</name>
    <value>sentry</value>
    <description>Sentry password for backend JDBC user </description>
  </property>
  <property>
    <name>sentry.store.jdbc.driver</name>
    <value>org.postgresql.Driver</value>
    <description>Backend JDBC driver - org.apache.derby.jdbc.EmbeddedDriver (only when dbtype = derby) JDBC Driver class for the backed DB</description>
  </property>
</configuration>

 

$ sentry --command schema-tool -dbType postgres -initSchema -conffile sentry-site.xml

Starting Sentry Service 

 

The Sentry Service runs in a secure environment like Kerberos. So at firstly it needs to generate a principal keytab file.

$ kinit admin/admin
$ kadmin
$ addprinc -randkey sentry/server-592.novalocal@HADOOP.COM 
$ xst -k sentry.keytab sentry/server-592.novalocal@HADOOP.COM 
$ mv sentry.keytab /etc/sentry/conf

 

The Sentry Service needs a configuration file sentry-site.xml to run. The properties sentry.store.jdbc.url, sentry.store.jdbc.driver,  sentry.store.jdbc.user and sentry.store.jdbc.password  must match the underlying Database in the sentry-site.xml.

The guide uses the Derby as the underlying Database.  So the sentry-site.xml as followings:

 

The sentry-site.xml:

 

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
  <property>
    <name>sentry.verify.schema.version</name>
    <value>false</value>
  </property>
  <property>
    <name>sentry.service.allow.connect</name>
    <value>sqoop2,impala,hive,solr</value>
  </property>
  <property>
    <name>sentry.store.jdbc.url</name>
    <value>jdbc:derby:;databaseName=sentry_db;create=true</value>
  </property>
 
  <property>
    <name>sentry.store.jdbc.user</name>
    <value>Sentry</value>
  </property>
  <property>
    <name>sentry.store.jdbc.password</name>
    <value>Sentry</value>
  </property>
  <property>
    <name>sentry.service.server.keytab</name>
    <value>/etc/sentry/conf/sentry.keytab</value>
  </property>
  <property>
    <name>sentry.service.server.rpcport</name>
    <value>8038</value>
  </property>

    <name>sentry.service.server.rpcaddress</name>
    <value>0.0.0.0</value>
  </property>
 
  <property>

    <value>org.apache.derby.jdbc.EmbeddedDriver</value>
  </property>
  <property>
    <name>sentry.service.admin.group</name>
    <value>sqoop2,hive,impala,solr</value>
  </property>
  <property>
    <name>sentry.service.security.mode</name>
    <value>kerberos</value>
  </property>
  <property>
    <name>sentry.service.server.principal</name>
    <value>sentry/server-592.novalocal@HADOOP.COM</value>
  </property>
</configuration>

Installing Sqoop2 

 

Download the Sqoop-1.99.6 release and install it.

$ wget http://archive.apache.org/dist/sqoop/1.99.6/sqoop-1.99.6-bin-hadoop200.tar.gz 
$ tar –xzvf sqoop-1.99.6-bin-hadoop200.tar.gz
$ cd sqoop-1.99.6-bin-hadoop200.tar.gz
$ export SQOOP2_HOME=`pwd`
$ export PATH=${PATH}:${SQOOP2_HOME}/bin
$ export SQOOP2_HOST="server-592.novalocal"

 

 

Generate Kerberos principals for Sqoop2 

 

The Sentry Service runs in a secure environment like Kerberos. So at firstly it needs to generate a principal keytab file.

$ kinit admin/admin
$ kadmin
$ addprinc -randkey sqoop2/server-592.novalocal@HADOOP.COM 
$ addprinc –randkey HTTP/server-592.novalocal@HADOOP.COM 
$ xst -k sqoop2.keytab sqoop2/server-592.novalocal@HADOOP.COM 
$ xst -k sqoop2.keytab HTTP/server-592.novalocal@HADOOP.COM 
$ mv sqoop2.keytab /etc/sqoop2/conf

Configure Kerberos authentication and Sentry Authorization 

 

The new latest release Sqoop-1.99.6 has support an authorization framework for third-party to integration. Sentry is a security open source product in the Apache Hadoop community that offers role-based authorization control. In this test, we will use the Sentry integration into Sqoop2.Edit the sqoop.properties file to configure Sentry binding authorization.

The default authentication and authorization configuration in the sqoop.properties looks like:

$ cat sqoop-1.99.6-bin-hadoop200/server/conf/sqoop.properties
#

Testing Sqoop2 with Sentry Authorization 

 

In the Sentry Authorization component, any user at firstly hasn’t privilege on resource

even if the user is an admin. So the first thing is to use the admin to grant privileges to other users which want to access Sqoop resource. The sqoop2 is the admin group

according to Sentry Service configuration:

  <property> 
    <name>sentry.service.admin.group</name> 
    <value>sqoop2,hive,impala,solr</value> 
  </property>

Sqoop2 authorization has ownership on resource object: 

 

When the user creates any resource object like link, job in Sqoop2, he is the owner of the resource. So he has the permanent privilege on that resource until it is deleted. Take the above test case for example. Test1 user has created a link hdfs2, so test1 is the owner of hdfs2. He can show and update link hdfs2 even if the admin user doesn’t grant privilege to test1. Test2 can show link hdfs1 because admin user grant read privilege to him.

What if the admin user revoking privilege from test1 and test2, the result shows as the following:

#admin user login
# sqoop2 as the running sqoop shell 
$ kinit sqoop2 
$ ./sqoop.sh client
sqoop:000> show privilege --principal-type role --principal test1
