> While using embedded metastore, while creating background threads to run async operations,
HiveServer2 ends up creating new instances of JDOPersistanceManager rather than using the
one from the foreground (handler) thread. Since JDOPersistanceManagerFactory caches JDOPersistanceManager
instances, they are never GCed.
