    +	   <para>-ROOT- keeps track of where the hbase:meta table is.  The -ROOT- table
structure is as follows:
+              <listitem><para><code>info:server</code> (server:port
of the RegionServer holding hbase:meta)</para></listitem>
+              <listitem><para><code>info:serverstartcode</code> (start-time
of the RegionServer process holding hbase:meta)</para></listitem>
+	   <para>The hbase:meta table keeps a list of all regions in the system. The hbase:meta
table structure is as follows:
+           <para>Periodically checks and cleans up the hbase:meta table.  See <xref
linkend="arch.catalog.meta" /> for more information on META.</para>
+            <listitem><para>Catalog tables: The -ROOT- and hbase:meta tables
are forced into the block cache and have the in-memory priority which means that they are
harder to evict. The former never uses
+(.regioninfo files), the region’s row in the hbase:meta table., and region’s deployment/assignments
on
+           and then the client goes back to hbase:meta to find the new location of the moved
region.</para>
