@Hitesh Rajpurohit

How is Atlas started in first place? Is it started using ambari or manually?

The error in the log says - the concerned user whoever is trying to restart atlas does not have permissions to stop the atlas service. This could happen in cases when atlas is started using some other user.

Hi Ayub,

Atlas was started with admin credentials only and now i'm trying to restart using Admin login only.

Can you please run the below command on the atlas host machine and paste the output here?

ps aux | grep -i Atlas

Also, please provide the output log when the service is started

Ok. I see that atlas is not running from command output. So, just remove the pid file of atlas and start it from ambari.

rm /var/run/atlas/atlas.pid

This should get the atlas started.
