Review Comment:
@cnauroth Thanks for review.
>@surendralilhore , thank you for the patch. I entered a few questions.
Additionally, can you please describe if you've been able to simulate the
problem in testing to confirm that this patch fixes it? (I assume unit testing
isn't practical for this.)
Yes, I simulated it by adding one thread in namenode and that thread will do
logout in 2 minute after stating namenode.
