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
