Wei-Chiu Chuang updated HDFS-9181:
----------------------------------
Description:
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.
