      Description

      HIVE-20707 added automatic partition management which uses thread pools to run parallel msck repair. It also modifies datanucleus connection pool size to avoid explosion of connections to backend database. But object store closes the persistence manager when it detects a change in datanuclues or jdo configs. So when PartitionManagementTask is running and when HS2 tries to connect to metastore HS2 will get persistence manager close exception.
