Subject [jira] Commented: (MAPREDUCE-564) Provide a way for the client to get the number of currently running maps/reduces
Date Wed, 23 Sep 2009 10:57:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12758656#action_12758656

Sharad Agarwal commented on MAPREDUCE-564:
------------------------------------------

Patch needs to be updated to trunk. Since MAPREDUCE-777 is committed I think these APIs should
be provided only in new job client apis. Old one is now deprecated.
