Rajesh Balamohan commented on HIVE-16323:
-----------------------------------------
SynchronizedMetaStoreClient is used only in load-dynamic-partition threads.
Should {{ObjectStore.shutdodown()}} set {{pm}} to null as this can be invoked
lots of times?. Also getPartition() called via loadPartition() should be using
"getSychronizedMSC()::getPartitionWithAuthInfo()" to be on safer side.
> HS2 JDOPersistenceManagerFactory.pmCache leaks after HIVE-14204

> Hive.loadDynamicPartitions creates threads with new embedded rawstore, but
> never close them, thus we leak PersistenceManager one per such thread.
