Description

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 :

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>
    ServiceCheck().execute()
  File "/usr/lib/python2.6/site-packages/resource_management/libraries/script/script.py", line 329, in execute
    method(env)
  File "/var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package/scripts/service_check.py", line 131, in service_check
    active_rm_webapp_address = self.get_active_rm_webapp_address()
  File "/var/lib/ambari-agent/cache/common-services/YARN/2.1.0.2.0/package/scripts/service_check.py", line 177, in get_active_rm_webapp_address
    raise Fail('Resource Manager state is not available. Failed to determine the active Resource Manager web application address from {0}'.format(','.join(rm_webapp_addresses)));
resource_management.core.exceptions.Fail: Resource Manager state is not available. Failed to determine the active Resource Manager web application address from ctr-e133-1493418528701-64577-01-000002.hwx.site:8090

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.
