Karthik Kambatla commented on YARN-1639:
----------------------------------------
Agree being able to use the same configs for both RMs would be simpler to
deploy. While working on YARN-1232, I discussed this with Bikas and Alejandro.
I can't remember the reason, but I think there was a reason we decided to go
with different ha.ids/configs. [~bikassaha], [~tucu00] - do you remember why?
> YARM RM HA requires different configs on different RM hosts

> Key: YARN-1639
> URL: https://issues.apache.org/jira/browse/YARN-1639
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Reporter: Arpit Gupta
> Assignee: Xuan Gong
>
> We need to set yarn.resourcemanager.ha.id to rm1 or rm2 based on which rm you
> want to first or second.
> This means we have different configs on different RM nodes. This is unlike
> HDFS HA where the same configs are pushed to both NN's and it would be better
> to have the same setup for RM as this would make installation and managing
> easier.
