> Key: AMBARI-9110
> URL: https://issues.apache.org/jira/browse/AMBARI-9110
> Project: Ambari
> Issue Type: Task
> Components: ambari-server
> Affects Versions: 2.0.0
> Reporter: Dmitry Lysnichenko
> Assignee: Dmitry Lysnichenko
> Fix For: 2.0.0

> DataNode cannot start due to an Operation not permitted when trying to change the ulimit. See screenshot.
> Non-Root Setup:
> {noformat}
> # vipw
> root:x:0:0:root:/root:/sbin/nologin
> # echo > /etc/securetty
> # vi /etc/ssh/sshd_config
> PermitRootLogin no
> {noformat}
> With that done I created a user named ‘ambari’ and used that during setup for the non-root user to run the Ambari Server as. I’ve setup this in /etc/sudoers:
> {noformat}
> ambari ALL=(ALL) NOPASSWD: ALL
> {noformat}
> I know this is best case for privileges, but want to get through one iteration before tightening it up.
> As well as this in /etc/sudoers.d/ambari (0440)
> {noformat}
> Defaults exempt_group = ambari
> Defaults !env_reset,env_delete-=PATH
> Defaults:ambari !requiretty
> {noformat}
