------------------------------------
This seems like a dupe of YARN-2424 . Andrey! Could you please confirm?
> Allow containers to be ran under real user even in insecure mode

> Key: YARN-1853
> URL: https://issues.apache.org/jira/browse/YARN-1853
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager, resourcemanager
> Affects Versions: 2.3.0
> Reporter: Andrey Stepachev
> Attachments: YARN-1853-trunk.patch, YARN-1853.patch

>
> Currently unsecure cluster runs all containers under one user (typically
> nobody). That is not appropriate, because yarn applications doesn't play well
> with hdfs having enabled permissions. Yarn applications try to write data (as
> expected) into /user/nobody regardless of user, who launched application.
> Another sideeffect is that it is not possible to configure cgroups for
> particular users.
