> Yarn service check is failing after moving the resource manager to a new
> host. This issue is occuring only on wire encrypted cluster. I performed the
> same operation on non wire encrypted cluster and service check is working
> fine.
> Steps to reproduce :
> 1) Move resource manager to a new host.
> 2) Run the service check.
> 3) Service check is failing with below exception :
> {code}
> Traceback (most recent call last):
> File
> "/var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package/scripts/service_check.py",
> line 181, in <module>

> {code}
> Even after moving the resource manager to new host, its still referring to
> the older resource manager host.
> *Workaround* : Property 'yarn.resourcemanager.webapp.https.address' was still
> referring to older resource manager host. I have manually updated this
> property to new host and restarted yarn. After this service check is going
> through fine.
