> 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.
