Subject [jira] [Commented] (MAPREDUCE-5130) Add missing job config options to mapred-default.xml
Date Sun, 12 May 2013 00:17:15 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13655406#comment-13655406
] 

Vinod Kumar Vavilapalli commented on MAPREDUCE-5130:
----------------------------------------------------

bq. Filed MAPREDUCE-5236
MAPREDUCE-5236 seemed incorrect when looked in isolation. Commented there. Can you just modify
that to mean that the test-case is failing? This is another general suggestion: File tickets
describing the problem and then propose the solution as a comment.

bq. computeNumSlotsPer* isn't used anywhere in the code. As there are no more slots in YARN,
and it is not a public API, would it not make the most sense to remove it?
+1, let's remove the method itself here.

> I came across that mapreduce.map.child.java.opts and mapreduce.reduce.child.java.opts
were missing in mapred-default.xml.  I'll do a fuller sweep to see what else is missing before
posting a patch.
> List so far:
> mapreduce.map/reduce.child.java.opts
> mapreduce.map/reduce.memory.mb
> mapreduce.job.jvm.numtasks
> mapreduce.input.lineinputformat.linespermap
> mapreduce.task.combine.progress.records
