> 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.
