      zypper install hive hcatalog

  2. Optional: Download and add the database connector JAR.

    • For MySQL:

      1. Execute the following command on the Hive metastore machine.

        • RHEL/CentOS: 

          yum install mysql-connector-java

        • For SLES: 

          zypper install mysql-connector-java

      2. Unzip and copy the downloaded JAR file the /usr/lib/hive/lib/ directory on your Hive host machine.
