Robert Joseph Evans commented on MAPREDUCE-3172:
------------------------------------------------
+1 for adding the cluster wide metrics to YarnClusterMetrics. However, the
user specific metrics I don't think fit well into YarClusterMetrics and they
are not available all of the time.
> Add cluster-level stats availabe via RPCs
