-------------------------------------
Summary: Better handling of exceptions thrown during upgrade
shutdown
Key: HDFS-9181
URL: https://issues.apache.org/jira/browse/HDFS-9181
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Wei-Chiu Chuang
Assignee: Wei-Chiu Chuang
Priority: Minor
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 way.
One way to handle it is by emitting a warning message. There could exist other
ways to handle it. This lira is created to discuss how to handle this case
better.
