Karthik Kambatla resolved YARN-1584.
------------------------------------
Resolution: Won't Fix
Target Version/s: (was: )
Marking this as "Won't Fix" as we didn't see a particular need for it on RM HA
deployments.
We can re-open this if need be.
> 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: 2.3.0
> 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 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.
