Junping Du commented on YARN-3173:
----------------------------------
Setup RM HA also involve other manual steps, e.g. start ZK server, etc., so I
am not sure how things proposed here help too much especially it need ssh login
between active RM and standby RM. [~xgong], do you have any comments here?
> start-yarn.sh script can't aware how many RMs to be started.

> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: BOB
> 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.
