Subject [jira] [Commented] (HDFS-5595) NameNode: implement AclManager as abstraction over INode ACL Map.
Date Mon, 16 Dec 2013 20:17:07 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5595?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13849675#comment-13849675
] 

Chris Nauroth commented on HDFS-5595:
-------------------------------------

This work is on hold for now, because the work on HDFS-5658 (ACL as an inode feature) has
moved faster.  I'm keeping this issue open for now until we do a full evaluation of pros and
cons between the two approaches.

As part of this work, I also had code in progress for the ACL modification logic.  That part
is valuable either way, so I'm moving that to HDFS-5673.

> Complete an initial implementation of {{AclManager}} to enable further development tasks.
 This will be a basic implementation using the INode ACL Map to track associations between
inodes and ACLs.  This will not fully implement all of the optimizations discussed in the
design doc.  Further optimization work will be tracked in separate tasks.
