Hello [~Tim Thorpe], [~dili]
Thanks for your notice. Steps to reproduce
1. Enable RM HA
2. Stop standby RM (or active)
3. Run Yarn service check
the service check fails with following error
{code}
Traceback (most recent call last):

as long as there is one RM not response, the service check will fail.

> Key: AMBARI-18929
> URL: https://issues.apache.org/jira/browse/AMBARI-18929
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Weiwei Yang
>
> When HA is enabled, yarn service_check.py fails if one of RM is down, even
> the other one is active. This gives user the wrong impression the yarn
> cluster is not healthy. Instead, service check should pass, or at least pass
> with warning that lets user know there is one RM down.
