Subject [jira] [Commented] (YARN-5877) Allow all nm-whitelist-env to get overridden during launch
Date Thu, 08 Dec 2016 17:25:58 GMT

    [ https://issues.apache.org/jira/browse/YARN-5877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15732823#comment-15732823
] 

Daniel Templeton commented on YARN-5877:
----------------------------------------

Latest patch is fine for me.  Looking at it, though, it occurs to me that we should really
be adding a test for the change in functionality.  Any chance you can add a test for {{writeLaunchEnv()}}
to {{TestContainerExecutor}}?  We should also test the whole thing in MAPREDUCE-6704.
