@asmarz,
One of our members posted a reply on how to add users in the thread you posted a similar question to later the same day.
As this is an older thread which was previously marked 'Solved', you would have a better chance of receiving a resolution by starting a new thread. This will also provide the opportunity for you to provide details specific to your environment about what you did in an attempt to add the relevant user accounts that could aid others in providing a more relevant, accurate answer to your question.

@rbalam, what you're trying to do looks good on paper but remember that cloud provisioning is always "instance" based (yes, the obvious :)), without getting too philosophical here think about how would Docker manage a pool of physical hardware and know where to deploy those containers? So long story short, I would strongly suggest setting up OpenStack; it's relatively straightforward and will save you time. Been there, done that a few times. Feel free to reach out if you need any help.

@rbalam you might have a stale pid with wrong permissions. I've seen this before. Delete the pid, check permissions on directory, make sure directory is not mounted as noexec.

I have experienced this problem after changing Ambari Server to run as a non privileged user "ambari-server". In my case I can see in the logs (/var/log/ambari-server/ambari-server.log) the following: 12 Sep 2018 22:06:57,515 ERROR [ambari-client-thread-6396] BaseManagementHandler:61 - Caught a system exception while attempting to create a resource: Error occured during stack advisor command invocation: Cannot create /var/run/ambari-server/stack-recommendations
This error happens because in CentOS/RedHat /var/run is really a symlink to /run which is a tmpfs filesystem mounted at boot time from RAM. So if I manually create the folder with the required privileges it won't survive a reboot and because the unprivileged user running Ambari Server is unable to create the required directory the error occurs. I was able to partially fix this using systemd-tmpfiles feature by creating a file /etc/tmpfiles.d/ambari-server.conf with following content: d /run/ambari-server 0775 ambari-server hadoop -
d /run/ambari-server/stack-recommendations 0775 ambari-server hadoop - With this file in place running "systemd-tmpfiles --create" will create the folders with the required privileges. According to the following RedHat documentation this should be automagically run at boot time to setup everything: https://developers.redhat.com/blog/2016/09/20/managing-temporary-files-with-systemd-tmpfiles-on-rhel7/ However sometimes this doesn't happens (I don't know why) and I have to run the previous command manually to fix this error.

I would recommend you to change the "desired_state" in the table "servicecomponentdesiredstate" under ambari database. You can update the values where service_name = 'RANGER_KMS'.
