Vinod,
You look to be using CDH3. Lets carry this on at cdh-u...@cloudera.org
[https://groups.google.com/a/cloudera.org/group/cdh-user/topics],
since the issue may just be CDH3 specific.
(Moving to that list, bcc'd common-user@)
Could you tell us about your job and about what the per-node RAM

Hi Harsh,
Wasn't MAPREDUCE-478 in 1.0 ? Maybe the Jira is not up to date.

Koji, Harsh
mapred-478 seems to be in v1, but those new settings have not yet been
added to mapred-default.xml. (for backwards compatibility?)

@Koji - Ah, I had not checked the sources, rather just the JIRA, which I've
updated now since there is indeed an svn commit listed there. Thanks for
correcting me there!
@George - I do not think it matters if these are present in default, but they
should be present, yes. Mind filing a JIRA if
but those new settings have not yet been
added to mapred-default.xml.
It's intentionally left out.
If set in mapred-default.xml, user's mapred.child.java.opts would be ignored
since mapred.{map,reduce}.child.java.opts would always win.
