> Now top metrics for namenode op is only supported aggregation for user,  the 
> top user op is useful. 
> But actually, the most useful is the callerContext aggregation, we can use 
> this to aggregate the running apps in yarn or the scheduling jobs by extend 
> the callerContext in such as (oozie or airflow), so that we can get the real 
> time top pressure to namenode.
