Chris Nauroth updated HADOOP-10220:
-----------------------------------
Attachment: HADOOP-10220.1.patch
Summary of changes:
# Add ACL bit member to {{FsPermission}}. Add new constructor, bit twiddling
and string parsing.
# Update {{TestFsPermission}} to fully cover new constructor, binary parsing
and string parsing for the new ACL bit. While I was in here, I noticed that
{{TestFsPermission#testFsPermission}} was not fully covering sticky bit
handling, so I also added tests for that.
# {{RawLocalFileSystem}} previously had a special case to ignore the '+' ACL
indicator when parsing results from a local file system that might have ACLs
enabled. Now that we have an ACL bit, we don't need this special case.
This patch is targeted for the HDFS-4685 feature branch, but it can apply
cleanly to trunk, so I'm going to try submitting it for a Jenkins run.
> Add ACL indicator bit to FsPermission.

> This patch will take a previously unused bit in the 16-bit {{FsPermission}}
> and use it to indicate the presence of an ACL on the file or directory. The
> CLI will use this to display an indicator in the permission string if an ACL
> is present. The NameNode will use it in ACL modification APIs, permission
> checks, and display of an indicator in the directory browser web UI.
