Subject [jira] [Updated] (HDFS-9181) Better handling of exceptions thrown during upgrade shutdown
Date Wed, 30 Sep 2015 21:18:04 GMT

     [ https://issues.apache.org/jira/browse/HDFS-9181?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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 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.

Thanks to [~templedf] for bringing this up.
