Hello Wei Wei
1.
"if active_rm_webapp_address is None:
raise Fail('Resource Manager state is not available, {0} cannot be
accessed'.format(','.join(rm_webapp_addresses)));"
Can you change it to
"Resource Manager state is not available. Failed to determine the active
Resource Manager web application address from {0}"....
2.
Could you fix the Python unit test errors? You can run the specific Python
unit test suite locally on your env with the following command. Run it under
the ambari root dir: mvn -pl ambari-server -DskipSurefireTests
-Dpython.test.mask=test_yarn_service_check.py clean test
{noformat}
-1 core tests. The test build failed in ambari-server
Test results:
https://builds.apache.org/job/Ambari-trunk-test-patch/9400//testReport/
{noformat}
Details on the test failures is in
https://builds.apache.org/job/Ambari-trunk-test-patch/9400//artifact/patch-work/testrun_ambari-server.txt

> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Weiwei Yang
> Attachments: AMBARI-18929_trunk.patch

>
> 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.
