Subject [jira] [Commented] (HDFS-4167) Add support for restoring/rollbacking to a snapshot
Date Sat, 10 Nov 2012 13:21:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13494680#comment-13494680
] 

Allen Wittenauer commented on HDFS-4167:
----------------------------------------

Discussion at the meeting was that rollback should be complete replacement, not partial. 
Partial data restores should be a copy.  (This is inline with other snapshot systems on other
file systems and meets expected behavior.)
