Subject [jira] [Commented] (YARN-4083) Add a discovery mechanism for the scheduler addresss
Date Thu, 27 Aug 2015 06:18:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14716146#comment-14716146

Jian He commented on YARN-4083:

One other thing to think about is what if NM died, should AM fall back to the RM?
Also, in case of RM HA, there will be multiple RM scheduler addresses, simply swapping out
a single scheduler address will not work.

> Today many apps like Distributed Shell, REEF, etc rely on the fact that the HADOOP_CONF_DIR
of the NM is on the classpath to discover the scheduler address. This JIRA proposes the addition
of an explicit discovery mechanism for the scheduler address
