> 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.
