Subject [jira] [Updated] (MAPREDUCE-5130) Add missing job config options to mapred-default.xml
Date Fri, 10 May 2013 06:25:16 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5130?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-5130:
-----------------------------------------------

    Status: Open  (was: Patch Available)

Thanks for doing this, Sandy!

Can you please file a ticket if the test is failing on trunk too? Tx.

mapreduce.job.jvm.numtasks isn't supported in MR over YARN. So we shouldn't document it. We
could remove it from code, but not without breaking JobClient API, so let's just keep it,
may be deprecate it and not document it

TestJobConf changes: Instead of removing code for computeNumSlotsPer*, you can make it work
with simple modifications?

> 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.memory.mb
> mapreduce.job.jvm.numtasks
> mapreduce.input.lineinputformat.linespermap
> mapreduce.task.combine.progress.records
