> 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.
