> Previously in HDFS-7533, a bug was fixed by suppressing exceptions during upgrade shutdown.
It may be appropriate as a temporary fix, but it would be better if the exception is handled
in some other ways.
> One way to handle it is by emitting a warning message. There could exist other ways to
handle it. This jira is created to discuss how to handle this case better.
> Thanks to [~templedf] for bringing this up.
