With SSL Encryption

This page explains additional steps for using SSL (Secure Sockets Layer) encryption in Hive on MR3. For simplicity, secure connection to database servers for Metastore and Ranger is not enabled. See SSL Encryption for details.

Certificates and secrets​

Create certificates and secrets by following the instructions in Creating certificates and secrets for SSL.

Copy hivemr3-ssl-certificate.jceks and hivemr3-ssl-certificate.jks in the directories key and ranger-key.

ls key/*{jceks,jks}
key/hivemr3-ssl-certificate.jceks  key/hivemr3-ssl-certificate.jks

ls ranger-key/*{jceks,jks}
ranger-key/hivemr3-ssl-certificate.jceks  ranger-key/hivemr3-ssl-certificate.jks

env.sh​

Update env.sh as follows.

vi env.sh

CREATE_KEYTAB_SECRET=true
CREATE_WORKER_SECRET=true

HIVE_SERVER2_SSL_TRUSTSTOREPASS=MySslPassword123
export HADOOP_CREDSTORE_PASSWORD=MySslPassword123
  • CREATE_KEYTAB_SECRET specifies whether or not to create a Secret from files in the directory key and should be set to true.
  • CREATE_WORKER_SECRET specifies whether or not to create a Secret for MR3 ContainerWorkers.
  • HIVE_SERVER2_SSL_TRUSTSTOREPASS and HADOOP_CREDSTORE_PASSWORD should be set to the password for KeyStores and TrustStores (specified when creating certificates and secrets).

HADOOP_CREDSTORE_PASSWORD should be appended to the values of the configuration keys mr3.am.launch.env and mr3.container.launch.env in conf/mr3-site.xml.

vi conf/mr3-site.xml

<name>mr3.am.launch.env</name>
  <value>LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/mr3-run/hadoop/apache-hadoop/lib/native,HADOOP_CREDSTORE_PASSWORD,AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY,AWS_REGION</value>
</property>

<property>
  <name>mr3.container.launch.env</name>
  <value>LD_LIBRARY_PATH=/opt/mr3-run/hadoop/apache-hadoop/lib/native,HADOOP_CREDSTORE_PASSWORD,AWS_ACCESS_KEY_ID,AWS_SECRET_ACCESS_KEY,AWS_REGION</value>
</property>

Configuring for SSL Encryption​
