>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: nodemanager, resourcemanager
>    Affects Versions: 2.3.0

>         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.
