Subject [jira] [Updated] (YARN-1584) Support explicit failover when automatic failover is enabled
Date Fri, 10 Jan 2014 18:16:52 GMT

     [ https://issues.apache.org/jira/browse/YARN-1584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Karthik Kambatla updated YARN-1584:
-----------------------------------

    Description: 
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 and then restarting the first RM is more involving and exposes the RM-ensemble
to SPOF for a longer duration. 

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

PS: HDFS supports -failover option.
