As Administrator, after upgrading from Ambari-managed HDP to CDP Private Cloud Base, you need to identify Hive
metastore operations that might fail due to Hive schema version incompatibility.
Incompatibility might exist if the upgrade process failed to make schema updates. You
need to turn on the Hive Metastore Schema validation process for the metastore during the
migration of your workloads to CDP. The Hive metastore captures any schema updates that occur
during the upgrade, and displays issues in the Hive metastore logs. With this information, you
can use the Apache Hive Schema tool to fix any problems.
