[jira] [Created] (HIVE-14267) HS2 open_operations metrics not decremented when an operation gets timed out

David Karoly created HIVE-14267:
-----------------------------------

             Summary: HS2 open_operations metrics not decremented when an operation gets timed out
                 Key: HIVE-14267
                 URL: https://issues.apache.org/jira/browse/HIVE-14267
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
            Reporter: David Karoly
            Priority: Minor


When an operation gets timed out, it is removed from handleToOperation hash map in OperationManager.removeTimedOutOperation(). However OPEN_OPERATIONS counter is not decremented. 
This can result in an inaccurate open operations metrics value being reported. Especially when submitting queries to Hive from Hue with close_queries=false option, this results in misleading HS2 metrics charts.
