Vaibhav Gumashta commented on HIVE-7353:
----------------------------------------

The test failure doesn't seem to be related - it's been failing on other precommits too. I'll
commit this in a while.

> While using embedded metastore, while creating background threads to run async operations,
HiveServer2 ends up creating new instances of JDOPersistanceManager which are cached in JDOPersistanceManagerFactory.
Even when the background thread is killed by the thread pool manager, the JDOPersistanceManager
are never GCed because they are cached by JDOPersistanceManagerFactory.
