mymeiyi opened a new pull request #163: HBASE-21995 Add a coprocessor to set HDFS ACL for hbase granted user
URL: https://github.com/apache/hbase/pull/163
 
 
   To make hbase granted user have the access to scan table snapshots, use HDFS ACLs to set user 'access r-x' or 'default r-x' ACLs over hfiles.
   The basic implementation is:
   1. For public directories such as 'data' and 'archive', set other users' permission to '--x' to make everyone have the permission to access the directory.
   2. For namespace or table directories such as 'data/ns/table', 'archive/data/ns/table' and '.hbase-snapshot/snapshotName', set user 'r-x' acl and default 'r-x' acl when grant, revoke, snapshot.
   The feature is configurable because it's implemented in a master coprocessor.
