> Stumbled upon this problem while refreshing queues with incorrect
> configuration. The exact scenario was:
> 1. Added a new queue "newQueue" without defining its capacity.
> 2. "bin/mapred queue -refreshQueues" fails correctly with "Illegal capacity
> of -1 for queue root.newQueue"
> 3. However, after defining the capacity of "newQueue" followed by a second
> "bin/mapred queue -refreshQueues" throws
> "org.apache.hadoop.metrics2.MetricsException: Metrics source
> QueueMetrics,q0=root,q1=newQueue already exists!" Also see
> Hadoop:name=QueueMetrics,q0=root,q1=newQueue,service=ResourceManager metrics
> being available even though the queue was not added.
> The expected behavior would be to refresh the queues correctly and allow
> addition of "newQueue".
