Subject [jira] [Updated] (MAPREDUCE-2405) MR-279: Implement uber-AppMaster (in-cluster LocalJobRunner for MRv2)
Date Fri, 01 Apr 2011 05:24:12 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2405?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Greg Roelofs updated MAPREDUCE-2405:

    Attachment: MR-2405-MR-1220-yarn.v10.MR-279-hadoop-yarn.patch.txt

De-personalized, cleaned up, and a better unit test.

Unfortunately, the git mirror is hosed, so I can't merge with the recently committed MAPREDUCE-2414
(i.e., this won't apply).  And I just remembered that I forgot to add boilerplate to the three
or four new files in here.  But other than those caveats (and keeping in mind that this is
a first cut, as previously noted), this is ready for pre-commit review.
