Vinod Kumar Vavilapalli updated YARN-1931:
------------------------------------------

    Priority: Major  (was: Blocker)
    Assignee: Sandy Ryza
     Summary: Private API change in YARN-1824 in 2.4 broke compatibility with previous releases  (was: YARN-1824 in 2.4 broke compatibility with previous releases)

I'm okay with this for now. But I'm requesting YARN app frameworks like TEZ, Spark and Twill to do a scan of their projects and get rid of YARN private APIs that are in use.

Assigning to Sandy. Reducing priority and fixing title.

> YARN-1824 broke compatibility with previous 2.x releases by changes the API's in org.apache.hadoop.yarn.util.Apps.{setEnvFromInputString,addToEnvironment}  The old api should be added back in.
> This affects any ApplicationMasters who were using this api.  It also breaks previously built MapReduce libraries from working with the new Yarn release as MR uses this api.
