> Project: Hadoop YARN
> Issue Type: Improvement
> Components: nodemanager, resourcemanager
> Affects Versions: 2.2.0
> Reporter: Andrey Stepachev
> Attachments: YARN-1853.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.
