Subject [jira] Commented: (MAPREDUCE-2102) Collect iops per task
Date Wed, 17 Nov 2010 18:21:17 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2102?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933064#action_12933064
] 

Arun C Murthy commented on MAPREDUCE-2102:
------------------------------------------

This isn't about Hadoop filesystem counters - we could capture low-level OS metrics for iops,
read/write bytes/sec, network iops etc.
