Subject [jira] [Commented] (HADOOP-12985) Support MetricsSource interface for DecayRpcScheduler Metrics
Date Wed, 20 Apr 2016 05:27:25 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12985?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15249271#comment-15249271

Jitendra Nath Pandey commented on HADOOP-12985:
-----------------------------------------------

The patch looks good to me. A minor comment that NameValuePair and TopN seem generally useful,
might make sense to move them to MetricsUtil or a separate class.

> This allows metrics collector such as AMS to collect it with MetricsSink. The per user
RPC call counts, schedule decisions and per priority response time will be useful to detect
and trouble shoot Hadoop RPC server such as Namenode overload issues.
