Subject [jira] [Created] (AMBARI-10834) Restart services automatically after a node reboot
Date Wed, 29 Apr 2015 15:27:08 GMT
Hari Sekhon created AMBARI-10834:
------------------------------------

             Summary: Restart services automatically after a node reboot
                 Key: AMBARI-10834
                 URL: https://issues.apache.org/jira/browse/AMBARI-10834
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-agent, ambari-server
    Affects Versions: 2.0.0
         Environment: HDP 2.2
            Reporter: Hari Sekhon


When a node reboots for any reason Ambari does not automatically restart the services on that
node after it comes back up.

I think it would be beneficial for the services on that node to be auto-restarted, equivalent
to if they were locally controlled via init scripts.

This could be done via Ambari server re-issuing the start commands when the agent comes back
in to contact and it sees the services are down but last requested state was started (the
agent is actually auto-started on boot since it's an init script) or the agent itself could
maintain the last requested state locally in state files and ensure that the services are
restarted if they are down during periodic process checks.
