> 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.
