> 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.
