Subject [jira] Commented: (MAPREDUCE-220) Collecting cpu and memory usage for MapReduce tasks
Date Wed, 18 Nov 2009 00:55:39 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779232#action_12779232

dhruba borthakur commented on MAPREDUCE-220:
--------------------------------------------

I am proposing that we hold off doing anything to this JIRA until MAPREDUCE-901 is committed.

In the meantime, the items marked B1 - B4 can be done as part of MAPREDUCE-1218. The B1-B4
are not task related metrics (rather, they are TaskTracker related) and are not dependent
on TaskMetrics changes proposed in MAPREDUCE-901.

> It would be nice for TaskTracker to collect cpu and memory usage for individual Map or
Reduce tasks over time.
