<p>
Access control lists are stored in an "internal" metadata table named
<code>_acl_</code>. Each table's permission grants are stored as a separate row,
keyed by the table name. KeyValues for permissions assignments are stored
in one of the formats:
<pre>
Key Desc
-------- --------
user table level permissions for a user [R=read, W=write]
group table level permissions for a group
user,family column family level permissions for a user
group,family column family level permissions for a group
user,family,qualifier column qualifier level permissions for a user
group,family,qualifier column qualifier level permissions for a group
</pre>

All values are encoded as byte arrays containing the codes from the
org.apache.hadoop.hbase.security.access.TablePermission.Action enum.
