> JDOPersistenceManager objects are cached in JDOPersistenceManagerFactory by
> DataNuclues.
> A new JDOPersistenceManager object gets created for every HMS thread since
> ObjectStore is a thread local.
> In non-embedded metastore mode, JDOPersistenceManager associated with a
> thread only gets cleaned up if IMetaStoreClient#close is called by the client
> (which calls ObjectStore#shutdown which calls JDOPersistenceManager#close
> which in turn removes the object from cache in
> JDOPersistenceManagerFactory#releasePersistenceManager
> https://github.com/datanucleus/datanucleus-api-jdo/blob/master/src/main/java/org/datanucleus/api/jdo/JDOPersistenceManagerFactory.java#L1271),
> i.e. the object will remain cached if client does not call close.
> For example: If one interrupts out of hive CLI shell (instead of using
> 'exit;' command), SessionState#close does not get called, and hence
> IMetaStoreClient#close does not get called.
> Instead of relying the client to call close, it's cleaner to automatically
> perform RawStore related cleanup at the server end via deleteContext() which
> gets called when the server detects a lost/closed connection.
