Subject [jira] [Created] (YARN-1584) Support explicit failover when automatic failover is enabled
Date Fri, 10 Jan 2014 17:46:57 GMT
Karthik Kambatla created YARN-1584:
--------------------------------------

             Summary: Support explicit failover when automatic failover is enabled
                 Key: YARN-1584
                 URL: https://issues.apache.org/jira/browse/YARN-1584
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
    Affects Versions: 2.4.0
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


YARN-1029 adds automatic failover support. However, users can't explicitly ask for a failover
from one RM to the other without stopping the other RM. Stopping the RM until the other RM
takes over exposes the RM-ensemble to SPOF for the duration. 

It would be nice to allow explicit failover through yarn rmadmin -failover command.

PS: HDFS supports -failover option.
