> Local Exception Stack: 
> Exception [EclipseLink-6004] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.QueryException
> Exception Description: The object [org.apache.ambari.server.orm.entities.ClusterConfigEntity@3646b3a8], of class [class org.apache.ambari.server.orm.entities.ClusterConfigEntity], with identity hashcode (System.identityHashCode()) [364,075,546], 
> is not from this UnitOfWork object space, but the parent session's.  The object was never registered in this UnitOfWork, 
> but read from the parent session and related to an object registered in the UnitOfWork.  Ensure that you are correctly
> registering your objects.  If you are still having problems, you can use the UnitOfWork.validateObjectSpace() method to 
> help debug where the error occurred.  For more information, see the manual or FAQ.

> Likely Cause:
> Stale clusterEntity reference points to a detached entity which gets tried to be merged, the Cascaded relationship throws the error on persist.
