Subject Re: what's counterpart for org.apache.hadoop.mapred.TaskTrackerMetricsInst in YARN
Date Tue, 04 Feb 2014 13:02:43 GMT
Unfortunately there isn't a direct equivalent available for plugging
in instrumentation classes in YARN's NodeManagers currently. The
closest I can locate is a comment hint in the NodeManagerMetrics class
that toys with the same idea:

If you'll absolutely need this in YARN, can you please file a YARN
JIRA with the motivation on why?
