Subject [jira] [Commented] (HDFS-4700) Fix the undo section of rename with snapshots
Date Tue, 16 Apr 2013 21:35:15 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633395#comment-13633395
] 

Tsz Wo (Nicholas), SZE commented on HDFS-4700:
----------------------------------------------

The patch looks good.  My only concern is that the reference count seems not being updated
in undo.

Also why add verify to addSpaceConsumed?  Is it for quota check?

> If a rename operation fails in the middle, the current undo section does not clear the
diff list. This jira aims to fix the undo logic and adds corresponding unit tests.
