Enable SSL on HiveServer2

You need to enable SSL on HiveServer by setting a few properties.

1. Log into the cluster as the hive user. Having hive user permissions when creating the Java keystore file sets up the proper user::group ownership, which allows HiveServer to access the file and prevents HiveServer startup failure.
2. Run the following command to create a keystore for hiveserver2: keytool -genkey -alias hbase -keyalg RSA -keysize 1024 -keystore hive.jks.
3. Edit the hive-site.xml, set the following properties to enable SSL:

   <property>
     <name>hive.server2.use.SSL</name>
     <value>true</value>
     <description></description>
   </property>
    
   <property>
     <name>hive.server2.keystore.path</name>
     <value>keystore-file-path</value>
     <description></description>
   </property>
   
   <property>
     <name>hive.server2.keystore.password</name>
     <value>keystore-file-password</value>
     <description></description>
   </property>

4. On the client-side, specify SSL settings for Beeline or JDBC client as follows:jdbc:hive2://<host>:<port>/<database>;ssl=true;sslTrustStore=<path-to-truststore>;trustStorePassword=<password>.
