Description

Aaron Myers and I found that when a directory is copied, its quotas settings aren't included.

[04:21:33] atm@simon:~/src/apache/hadoop.git$ hadoop fs -ls /user
Found 2 items

This also means that a user will not retain quotas settings when the user takes snapshots and restores a subtree using snapshots because we use copy (not allowed to move snapshots).
