Subject [jira] [Created] (HADOOP-9945) HAServiceState should have a state for stopped services
Date Mon, 09 Sep 2013 20:10:51 GMT
Karthik Kambatla created HADOOP-9945:

             Summary: HAServiceState should have a state for stopped services
                 Key: HADOOP-9945
                 URL: https://issues.apache.org/jira/browse/HADOOP-9945
             Project: Hadoop Common
          Issue Type: Improvement
          Components: ha
    Affects Versions: 2.1.0-beta
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla

HAServiceState, currently, has states for Initializing, Active, and Standby. 

For RM HA, it is useful to have another state "STOPPED". This is because, YARN has a separate
service model where Services are stopped and can't be restarted. When the Active/Standby RM
is stopped, it can no longer go back to the Active/Standby state; setting the HAServiceState
to Initializing is misleading.
