Sunil G commented on YARN-5208:
-------------------------------
Using default up resolver was used earlier and it might be enough for client
tests. With first patch, many of the regularly failing test classes are
passing. But as you mentioned, there will be impact in HA or some other test
cases where we use host name through conf. I think such cases can be fixed.
> Run TestAMRMClient TestNMClient TestYarnClient TestClientRMTokens
> TestAMRMTokens tests with hadoop.security.token.service.use_ip enabled

> All YARN test cases are running with *hadoop.security.token.service.use_ip*
> disabled. As a result few tests {{TestAMRMClient TestNMClient TestYarnClient
> TestClientRMTokens TestAMRMTokens}} cases are consistently failing because of
> unable to resolve hostname(see HADOOP-12687 YARN-4306 YARN-4318)
> I would suggest to run tests with *hadoop.security.token.service.use_ip*
> enabled by default. And for the HA test cases which require mandatory
> disabling , change test cases as required by setting
> {code}
> conf.setBoolean(
> CommonConfigurationKeys.HADOOP_SECURITY_TOKEN_SERVICE_USE_IP, false);
> SecurityUtil.setConfiguration(conf);
> {code}
