Subject [jira] [Commented] (YARN-3173) start-yarn.sh script can't aware how many RMs to be started.
Date Wed, 11 Feb 2015 15:37:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-3173?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316372#comment-14316372

Allen Wittenauer commented on YARN-3173:

This actually can be fixed if start-yarn uses some of the same tricks that start-dfs uses.
 However, it's a lot easier with HADOOP-11565 committed.

>            Priority: Minor
> When config more than one RM, for example in the HA cluster, using the start-yarn.sh
script to start yarn cluster,but the cluster only start up with one resourcemanager  on the
node which start-yarn.sh be executed. I think yarn should sense how many RMs been configured
at the beginning, and start them all in start-yarn.sh script.
