Ashish Vaidya commented on HIVE-4398:
-------------------------------------


I think there's one big caveat with the new implementation -- we shouldn't have 
anyone call OperationManager.closeOperation() directly; they should always go 
through a HiveSession object.
                
> HS2 Resource leak: operation handles not cleaned when originating session is 
> closed
