Subject [jira] [Updated] (MAPREDUCE-4810) Add admin command options for ApplicationMaster
Date Tue, 08 Jan 2013 11:52:14 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-4810?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vinod Kumar Vavilapalli updated MAPREDUCE-4810:
-----------------------------------------------

    Status: Open  (was: Patch Available)

Mostly looks good.
 - Rename admin.java.opts to admin-command-opts to be inline with the current name.
 - Similarly change the variable names everywhere to refer to command-opts
 - Typo 'optiions' in the patch.

> It would be nice if the MR ApplicationMaster had the notion of admin options in addition
to the existing user options much like we have for map and reduce tasks, e.g.: mapreduce.admin.map.child.java.opts
vs. mapreduce.map.java.opts.  This allows site-wide configuration options for MR AMs but still
allows a user to easily override the heap size of the AM without worrying about dropping other
admin-specified options.
