Sandy Ryza commented on YARN-1931:
----------------------------------
+1 to adding the old API back in. The old API isn't the right one going
forward, and we should deprecate it, but keeping it will save a lot of trouble
for those who want to run an older version of Spark or MR on a recent version
of YARN.
> YARN-1824 in 2.4 broke compatibility with previous releases
> -----------------------------------------------------------
>
> Key: YARN-1931
> URL: https://issues.apache.org/jira/browse/YARN-1931
> Project: Hadoop YARN
> Issue Type: Bug
> Components: applications
> Affects Versions: 2.4.0
> Reporter: Thomas Graves
> Priority: Blocker
>
> 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.
