@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. ... View more

@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. ... View more

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'. ... View more
