Subject [jira] Commented: (HADOOP-5738) Split waiting tasks field in JobTracker metrics to individual tasks
Date Mon, 04 May 2009 07:53:30 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5738?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12705512#action_12705512

Hong Tang commented on HADOOP-5738:
-----------------------------------

@Sreekanth, sorry for my distracting comments. I guess Chris is right and we should keep "waiting_tasks"
for now, and possibly remove it in future major releases.

> Currently, job tracker metrics reports waiting tasks as a single field in metrics. It
would be better if we can split waiting tasks into maps and reduces.
