Subject [jira] [Created] (AMBARI-2973) Ambari server and agent are not stopped during package uninstall
Date Wed, 21 Aug 2013 10:48:53 GMT
Vladimir Tkhir created AMBARI-2973:
--------------------------------------

             Summary: Ambari server and agent are not stopped during package uninstall
                 Key: AMBARI-2973
                 URL: https://issues.apache.org/jira/browse/AMBARI-2973
             Project: Ambari
          Issue Type: Bug
          Components: agent, controller
    Affects Versions: 1.4.1
            Reporter: Vladimir Tkhir
             Fix For: 1.4.1


When ambari-agent and ambari-server packages are uninstalled, uninstall scriplets don't stop
running services. That's why processes remain running even after package removal. 
That may cause issues during upgrade (if administrator misses the "stop services" step)
