Subject [jira] Commented: (HDFS-556) Provide info on failed volumes in the web ui
Date Thu, 27 Aug 2009 18:23:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-556?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12748490#action_12748490

Boris Shkolnik commented on HDFS-556:

Well, there are few ways of solving this.
1. print out the "cause" exception together with the error message. That will tell the person
that the problem was with Quota. We cannot make suggestions about "-skipTrash" in this case.
2. catch and rethrow exception in delete function when trying to move to Trash. This way we
know that the problem is with trash and we can issue a message suggesting using "-skipTrash".
The disadvantage is that this way we issue two separate messages.

> HDFS-457 provided better handling of failed volumes but did not provide a corresponding
view of this functionality on the web ui, such as a view of which datanodes have failed volumes.
 This would be a good feature to have.
