Subject [jira] Commented: (HDFS-883) Datanode shutdown should log problems with Storage.unlockAll()
Date Tue, 26 Jan 2010 12:50:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12805008#action_12805008

Steve Loughran commented on HDFS-883:
-------------------------------------

As I said in the patch; no tests here as all that is happening is logging shutdown problems
that are fairly hard to simulate, but when they happen, should at least be logged

> Datanode shutdown should log problems with Storage.unlockAll()

> When shutting down, Datanode calls {{Storage.unlockAll()}}, but discards any exceptions
thrown in the process.
> These exceptions could be useful in diagnosing problems, and should be logged.
