Jian He commented on YARN-5995:
-------------------------------
Actually, it can be most useful if this is a time series metrics that can be
used by external framework to show the metrics over time - to show when RM
incurs high write latencies, as we always do postmortem analysis.
If so, we can merely output the absolute value of 'time cost for each store op'
or 'amount of data written for each op', external tool can use this metrics to
plot metrics over time.
