Subject [jira] [Comment Edited] (YARN-6625) yarn application -list returns a tracking URL for AM that doesn't work in secured and HA environment

---------------------------------------------------------------

Overall looks good.  Here's some comments:
# In {{ClientRMProxy}}, instead of {{return new Text(schedulerService + "," + adminService);}},
let's use {{Joiner}} like what's used below it in {{getTokenService}}.
# {{ClientRMProxy#getAMRMTokenService}} is used in a few places.  Have you made sure that
they're all okay with adding the RM admin address?
# I'm not expert on the way our RPCs work, but is {{HAServiceProtocolPB}} the right thing
to check in {{AdminSecurityInfo}}?  Just from the name, it seems funny to use an "HA" Protocol
here because what happens in a non-HA cluster?  In any case, based on the {{getKerberosInfo}}
above it and the name itself, wouldn't {{ResourceManagerAdministrationProtocolPB}} be the
right thing to use?
# It would also be good to add some kind of test, though that might be tricky

> The tracking URL given at the command line should work secured or not. The tracking URLs
are like http://node-2.abc.com:47014 and AM web server supposed to redirect it to a RM address
like this http://node-1.abc.com:8088/proxy/application_1494544954891_0002/, but it fails to
do that because the connection is rejected when AM is talking to RM admin service to get HA
status.
