--------------------------------------
Summary: Add ACL indicator bit to FsPermission.
Key: HADOOP-10220
URL: https://issues.apache.org/jira/browse/HADOOP-10220
Project: Hadoop Common
Issue Type: Sub-task
Components: fs
Affects Versions: HDFS ACLs (HDFS-4685)
Reporter: Chris Nauroth
Assignee: Chris Nauroth
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.
