Subject [jira] Commented: (MAPREDUCE-1218) Collecting cpu and memory usage for TaskTrackers
Date Wed, 18 Nov 2009 04:00:39 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12779279#action_12779279
] 

Hong Tang commented on MAPREDUCE-1218:
--------------------------------------

Such information may be usable across both MapReduce and HDFS, and could be a standalone *real-time*
load collection mechanism. A logical extension here is to include io-load in the reporting
too.
