Jian He commented on YARN-6072:
-------------------------------
bq. // Set HA configuration should be done before login
I don't know why this comment is added. In my understanding, it should at least
be fine to move "add admin service" before "add elector service".
bq. Hmm yes but additionally we get the log trace too,
Yes, I know. I meant it can be such as: new ServiceFailedException("RefreshAll
operation failed ", ex);
Anyway, based on your explanation, the current patch is also fine to me. these
comments are minor.
