Xuan Gong commented on YARN-1893:
---------------------------------
bq. Seems we never had a test for testing AMRMToken works in failover scenario.
To unblock this , can you at least manually test AMRMToken works in failover?
We can add the test separately.
Right. Create a separate ticket to track this:
https://issues.apache.org/jira/browse/YARN-1895
Do the manual test to verify AMRMToken works in failover
bq. One nit, you can use addPersistedPassword instead of creating a new
getPasswords method in AMRMTokenSecretManager.
Right. Create a new patch to fix it.
