Subject [jira] [Commented] (YARN-1696) Document RM HA
Date Wed, 26 Mar 2014 22:00:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-1696?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13948533#comment-13948533

Vinod Kumar Vavilapalli commented on YARN-1696:
-----------------------------------------------

I think the long term goal is to unify them but we aren't there yet. There are users who want
to enable RM restart only without failover today. Given that, I think we should keep them
separate till we have a complete story. When things come together long term, we can link these
together by using a top level doc. Even then, I think after we go through the remaining phases
in RM restart, the doc at YARN-1017 will grow more and it's better to do what HDFS did - split
into well-defined pages.

This doc should instead be renamed "ResourceManager fail-over" and only focus on that for
now.
