Subject [jira] [Commented] (HDFS-4167) Add support for restoring/rolling back to a snapshot
Date Sat, 03 May 2014 14:38:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13988703#comment-13988703
] 

Tsz Wo Nicholas Sze commented on HDFS-4167:
-------------------------------------------

Suppose a (closed) file foo has size 100MB and a snapshot s0 is taken.  Then foo is appended
to 110MB.  Now, restore s0 but foo is still 110MB.  I think it may not be a good behavior.
