Wangda Tan commented on YARN-5002:
----------------------------------
[~kasha],
We totally agree that enforce same ACL for running and completed applications
in removed queues is the best solution. However, since we don't store ACL info
for removed queues today, we cannot get ACL info for removed queues.
I would like to suggest to fix this NPE issue first, and for the longer term,
after we can store ACL info for removed queues as well, we can enforce same ACL
check.
Thoughts?
