Testing the YAML and the cluster connection

It makes sense to test the YAML and cluster connection before starting the migration using HMS Mirror. Connection troubleshooting is easier before, rather than after, running HMS Mirror.

Using a Hive client, such as DBeaver, beeline, or Tableau, connect the left cluster to the right cluster, and then vice versa.
If you use ZooKeeper Service Discovery on the HDP source cluster, use a plain URL in your connection string.
For example:jdbc:hive2://<hive-server2-hostname>:10000/
