<div class="block">Set HDFS ACLs to hFiles to make HBase granted users have permission to scan snapshot
<p>
To use this feature, please mask sure HDFS config:
<ul>
<li>dfs.namenode.acls.enabled = true</li>
<li>fs.permissions.umask-mode = 027 (or smaller umask than 027)</li>
</ul>
</p>
<p>
The implementation of this feature is as followings:
<ul>
<li>For common directories such as 'data' and 'archive', set other permission to '--x' to make
everyone have the permission to access the directory.</li>
<li>For namespace or table directories such as 'data/ns/table', 'archive/ns/table' and
'.hbase-snapshot/snapshotName', set user 'r-x' access acl and 'r-x' default acl when following
operations happen:
<ul>
<li>grant user with global, namespace or table permission;</li>
<li>revoke user from global, namespace or table;</li>
<li>snapshot table;</li>
<li>truncate table;</li>
</ul>
</li>
<li>Note: Because snapshots are at table level, so this feature just considers users with global,
namespace or table permissions, ignores users with table CF or cell permissions.</li>
