When hive.server2.transport.mode is binary and hive.server2.authentication is KERBEROS, SSL encryption does did not currently work until Hive 2.0. Set hive.server2.thrift.sasl.qop to auth-conf to enable encryption. See HIVE-14019 for details.


  1. Create the self signed certificate and add it to a keystore file using:  keytool -genkey -alias -keyalg RSA -keystore keystore.jks -keysize 2048 Ensure the name used in the self signed certificate matches the hostname where HiveServer2 will run.
  2. List the keystore entries to verify that the certificate was added. Note that a keystore can contain multiple such certificates: keytool -list -keystore keystore.jks

  3. Export this certificate from keystore.jks to a certificate file: keytool -export -alias -file -keystore keystore.jks

  4. Add this certificate to the client's truststore to establish trust: keytool -import -trustcacerts -alias -file -keystore truststore.jks

  5. Verify that the certificate exists in truststore.jks: keytool -list -keystore truststore.jks

  6. Then start HiveServer2, and try to connect with beeline using: jdbc:hive2://<host>:<port>/<database>;ssl=true;sslTrustStore=<path-to-truststore>;trustStorePassword=<truststore-password>



hive.server2.authentication – Set this to PAM. – Set this to a list of comma-separated PAM services that will be used. Note that a file with the same name as the PAM service must exist in /etc/pam.d.

Setting up HiveServer2 job credential provider

Starting Hive 2.2.0 onwards (see HIVE-14822) Hiveserver2 supports job specific hadoop credential provider for MR and Spark jobs. When using encrypted passwords via the Hadoop Credential Provider, HiveServer2 needs to forward enough information to the job configuration so that jobs launched across cluster can read those secrets. Additionally, HiveServer2 may have secrets that the job should not have such as the Hive Metastore database password. If your job needs to access such secrets, like S3 credentials, then you can configure them using the configuration steps below:

  1. Create a job-specific keystore using Hadoop Credential Provider API at a secure location in HDFS. This keystore should contain the encrypted key/value pairs of the configurations needed by jobs. Eg: in case of S3 credentials the keystore should contain fs.s3a.secret.key and fs.s3a.access.key with their corresponding values.
  2. The password to decrypt the keystore should be set as a HiveServer2 environment variable called HIVE_JOB_CREDSTORE_PASSWORD
  3. Set  hive.server2.job.credential.provider.path to URL pointing to the type and location of keystore created in (1) above. If there is no job-specific keystore, HiveServer2 will use the one set using hadoop.credential.provider.path in core-site.xml if available.
  4. If the password using environment variable set in step 2 is not provided, HiveServer2 will use HADOOP_CREDSTORE_PASSWORD environment variable if available.
  5. HiveServer2 will now modify the job configuration of the jobs launched using MR or Spark execution engines to include the job credential provider so that job tasks can access the encrypted keystore with the secrets. 

hive.server2.job.credential.provider.path – Set this to your job-specific hadoop credential provider. Eg: jceks://hdfs/user/hive/secret/jobcreds.jceks.

HIVE_JOB_CREDSTORE_PASSWORD – Set this HiveServer2 environment variable to your job specific Hadoop credential provider password set above.

Scratch Directory Management


A Web User Interface (UI) for HiveServer2 provides configuration, logging, metrics and active session information. The Web UI is available at port 10002 ( by default.  


  • . 
  • Hive Metrics can by viewed by using the "Metrics Dump" tab. 
  • Logs can be viewed by using the "Local logs" tab.

The interface is currently under development with HIVE-12338.
