[jira] [Created] (HADOOP-9933) Augment Service model to support starting stopped services

Karthik Kambatla created HADOOP-9933:
----------------------------------------

             Summary: Augment Service model to support starting stopped services
                 Key: HADOOP-9933
                 URL: https://issues.apache.org/jira/browse/HADOOP-9933
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 2.1.0-beta
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


For ResourceManager-HA (YARN-149 and co), we would want to start/stop/start RM's active services as it transitions to Active/Standby/Active respectively. In the current service model, we can't start the services that are already stopped.

Would be nice to augment this. To avoid accidental restart of stopped services, we can add another API: start(boolean restartIfStopped). Thoughts?
