Tsz Wo (Nicholas), SZE commented on HDFS-4141:
----------------------------------------------

> Could I please have a day or two to review this patch? It's a pretty big patch ...

A 30kB patch is pretty big?!  Anyway, I believe you don't want to slow down the development.
 I will commit it later today.  The patch is going to be committed to the branch.  You may
take your time to review the branch.

> With snapshots, the same directory could have different states, e.g. different sets of
children, in different snapshots.  We implement a directory diff algorithm in this JIRA.
