Re: what's counterpart for org.apache.hadoop.mapred.TaskTrackerMetricsInst in YARN
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:
https://github.com/apache/hadoop-common/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/metrics/NodeManagerMetrics.java#L53

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