Subject [jira] Commented: (MAPREDUCE-220) Collecting cpu and memory usage for MapReduce tasks
Date Mon, 09 Aug 2010 18:40:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12896659#action_12896659

Eli Collins commented on MAPREDUCE-220:

Looks good.     Minor nit: I might rename ProcResourceStatus to something like ProcResourceValues.
 Also, this inner class technically needs interface annotations (private and unstable). Sanjay
and Tom can correct me if I'm wrong but I don't think we decided that classes inherit the
annotations of the outer class.

Reduce tasks over time.
