Upgrade Hive
Hive consists of multiple services. Here is the general approach for the Hive rolling upgrade process:
Upgrade each Hive Metastore server to the new version and restart it
Start the new Hive Server 2 instance on each node and deregister the old Hive Server 2 instance
Upgrade WebHCat to the new version and restart the WebHCat server
Validate the upgrade process
