             Summary: Improve process checks / verification while using pid's
                 Key: AMBARI-15337
                 URL: https://issues.apache.org/jira/browse/AMBARI-15337
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-server
         Environment: NA
            Reporter: Venkatraman P


Today the service checks depends on the /var/run/component/component.pid file. Many a times, there are stale pid's which are causing services startups to fail from Ambari.
Especially during Ambari upgrade when such a failure happens, it becomes difficult to restart the services.

We need to improve the way we handle the pid files are completely move out to a different method. 

Whent he pid and the process started aren't matching - that needs to be reported by Ambari and may be it should remove the stale pid files.
