Subject [jira] [Commented] (YARN-1232) Configuration to support multiple RMs
Date Mon, 30 Sep 2013 17:55:24 GMT

    [ https://issues.apache.org/jira/browse/YARN-1232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13782047#comment-13782047
] 

Karthik Kambatla commented on YARN-1232:
----------------------------------------

Summarizing the JIRA to make it simpler for folks to follow. As the description states, the
focus of this JIRA is to add configs to allow specifying multiple RMs and their RPC addresses.
The approach is to add the notion of RM-ids through {{yarn.resourcemanager.ha.nodes}}, and
add a node-id suffix to each RPC address config. When starting the cluster, the server-side
config should explicitly set {{yarn.resourcemanager.ha.node.id}} to specify the node-id of
the RM being started.

I believe the patch is ready for review.

> We should augment the configuration to allow users specify two RMs and the individual
RPC addresses for them.
