Subject [jira] [Commented] (HADOOP-8288) Remove references of mapred.child.ulimit etc. since they are not being used any more
Date Thu, 19 Apr 2012 15:32:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8288?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13257543#comment-13257543

Ravi Prakash commented on HADOOP-8288:

Hey Bobby! I have no idea what patch is complaining about! 
bq. cp: cannot stat `/home/jenkins/buildSupport/lib/*': No such file or directory
Could it be because I am removing two files in hadoop-tools ?

The patch applies just fine. I have to svn rm TestUlimit.java and UlimitApp.java but it works

> 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.
