Jing Zhao commented on HDFS-4897:
---------------------------------
Hi Stephen, I tried "hadoop fs -mv" and in my test the same quota setting were
included in the new directory:
{code}
$ hadoop dfsadmin -setQuota 100 /user/jing
$ hadoop fs -count -q /user/jing
100 99 none inf 1
0 0 /user/jing
$ hadoop fs -mv /user/jing /user/jing-copy2
$ hadoop fs -count -q /user/jing-copy2
100 99 none inf 1
0 0 /user/jing-copy2
{code}
So is this issue only about copying a directory?

> [~atm] and I found that when a directory is copied, its quotas settings

> 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).
