Daniel Dai updated HIVE-16323:
------------------------------
Attachment: HIVE-16323.4.patch
Good point to set pm to null. However, getPartition seems involve a big block
and synchronize it needs nontrivial code refactory, I don't want to touch it
for now.
> HS2 JDOPersistenceManagerFactory.pmCache leaks after HIVE-14204
