Rushabh S Shah commented on HADOOP-13437:
-----------------------------------------
We recently ran into this bug in branch-2.8.
I think we should back-port this patch back to branch-2.8.
Also I think we should back-port all the bug fixes back to branch-2.8 and
branch-2.7 if the bug was introduced in 2.6.
[~xiaochen], [~andrew.wang]: Do you know of any more surprises (bug fixes) in
EZ feature which are not back-ported all the way back to branch-2.8 ?

> When hot-reloading, {{KMSACLs#setKeyACLs}} ignores whitelist and default key
> entries if they're present in memory.
> We should reload them, hot-reload and cold-start should not have any
> difference in behavior.
