Subject [jira] [Updated] (MAPREDUCE-5152) MR App is not using Container from RM
Date Tue, 16 Apr 2013 02:14:15 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5152?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Vinod Kumar Vavilapalli updated MAPREDUCE-5152:

    Attachment: MAPREDUCE-5152-20130415.txt

Here's patch to fix this:
 - Changed MR App's ContainerLauncher to use the Container given by the RM
 - Changed an existing test-case to also validate NodeId, port etc. This test passes with
the code changes and fails without.

> The goal of YARN-486 was to make AMs just pass information encapsulated in Container
along to NM instead of doing it themselves by duplicating information. We still do not do
this pass-through as intended as YARN-486 avoided the individual field duplication but failed
to avoid the duplication of container itself.
