Varun Saxena commented on YARN-3893:
------------------------------------

[~sunilg], even I was suggesting earlier in my comment that we reinit only 
while transitioning to active.

But then I thought that if we reinit on standby and there is a problem in 
initialization, a failure can indicate the admin to correct his config. An 
audit log will be printed.
If we do not reinit, a success audit log on transition to standby would be 
printed, which may indicate no problem in config to admin.
Thoughts ?

We can procrastinate reiniting till transition to active as well. But its 
better to indicate a failure even on standby IMHO. I do not see any harm in it.
I am fine either ways because reiniting really matters when transitioning to 
active.
