Subject [jira] [Commented] (HDFS-4685) Implementation of ACLs in HDFS
Date Wed, 04 Dec 2013 17:48:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13839112#comment-13839112
] 

Colin Patrick McCabe commented on HDFS-4685:
--------------------------------------------

Thanks for tackling this Chris.  it looks good overall.

Now that we have HDFS-5286 (flatten inode directory) in, doesn't it make sense to have the
ACLs associated with an {{INode}} be stored as {{Features}}, rather than using a separate
data structure? I didn't see any mention in the design doc-- maybe I missed it.

> Currenly hdfs doesn't support Extended file ACL. In unix extended ACL can be achieved
using getfacl and setfacl utilities. Is there anybody working on this feature ?
