Subject [jira] [Commented] (HDFS-4897) Copying a directory does not include the directory's quota settings
Date Mon, 10 Jun 2013 18:28:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4897?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13679740#comment-13679740
] 

Stephen Chu commented on HDFS-4897:
-----------------------------------

bq. Can you explain what you mean by "restore a subtree using snapshots"? Currently there
is no restore supported. If you want to restore some data, you need to copy, which should
follow the current copy semantics.

I meant using copy to restore some data. Sorry for being unclear.

> 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).
