Kihwal Lee commented on HADOOP-13742:
-------------------------------------
bq. That's a good idea and may be required to for detailed analysis about each
user's usage. In simple terms there could be separate instances of
RpcDetailedMetrics for each user, Just an Idea. I feel this could be done in a
follow-up jira and detailed discussions could be made.
I didn't mean to suggest per-user RpcDetailedMetrics. I meant per-user
connection metrics with cumulative counts. But the instantaneous numbers are
fine as well.
One minor thing in the latest patch is the new code in the test. {{server}}
needs to be {{final}}, if you want this patch to go beyond trunk.
> Expose "NumOpenConnectionsPerUser" as a metric
