Subject [jira] Commented: (MAPREDUCE-220) Collecting cpu and memory usage for MapReduce tasks
Date Tue, 04 May 2010 17:17:02 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12863897#action_12863897
] 

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

I like the idea of sending this information via Counters.

This data could be used by schedulers to make decisions on what/when to schedule new tasks
or preempt existing tasks. For this use-case, it would be nice if we can send them to the
JT more frequently that 1 minute. any ideas here?
