Subject [jira] [Commented] (MAPREDUCE-4134) Remove references of mapred.child.ulimit etc. since they are not being used any more
Date Tue, 17 Apr 2012 16:14:18 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13255685#comment-13255685
] 

Ravi Prakash commented on MAPREDUCE-4134:
-----------------------------------------

The console says
MAPREDUCE-4134 patch is being downloaded at Tue Apr 17 15:42:12 UTC 2012 from
http://issues.apache.org/jira/secure/attachment/12522286/MAPREDUCE-4134.patch
cp: cannot stat `/home/jenkins/buildSupport/lib/*': No such file or directory

Something is amiss with Jenkins :( The patch applies cleanly to branch-0.23 and almost cleanly
to trunk.

> Courtesy Philip Su, we found that (mapred.child.ulimit, mapreduce.map.ulimit, mapreduce.reduce.ulimit)
were not being used at all. The configuration exists but is never used. Its also mentioned
in mapred-default.xml and templates/../mapred-site.xml . Also the method getUlimitMemoryCommand
in Shell.java is now useless and can be removed.
