implements <a href="../../../../../org/apache/hadoop/hbase/rsgroup/RSGroupInfoManager.html" title="interface in org.apache.hadoop.hbase.rsgroup">RSGroupInfoManager</a></pre>
<div class="block">This is an implementation of <a href="../../../../../org/apache/hadoop/hbase/rsgroup/RSGroupInfoManager.html" title="interface in org.apache.hadoop.hbase.rsgroup"><code>RSGroupInfoManager</code></a> which makes use of an HBase table as the
persistence store for the group information. It also makes use of zookeeper to store group
information needed for bootstrapping during offline mode.
<h2>Concurrency</h2> RSGroup state is kept locally in Maps. There is a rsgroup name to cached
RSGroupInfo Map at <a href="../../../../../org/apache/hadoop/hbase/rsgroup/RSGroupInfoManagerImpl.RSGroupInfoHolder.html#groupName2Group"><code>RSGroupInfoManagerImpl.RSGroupInfoHolder.groupName2Group</code></a>.
These Maps are persisted to the hbase:rsgroup table (and cached in zk) on each modification.
<p/>
Mutations on state are synchronized but reads can continue without having to wait on an instance
monitor, mutations do wholesale replace of the Maps on update -- Copy-On-Write; the local Maps of
state are read-only, just-in-case (see flushConfig).
<p/>
Reads must not block else there is a danger we'll deadlock.
<p/>
Clients of this class, the <a href="../../../../../org/apache/hadoop/hbase/rsgroup/RSGroupAdminEndpoint.html" title="class in org.apache.hadoop.hbase.rsgroup"><code>RSGroupAdminEndpoint</code></a> for example, want to query and then act
on the results of the query modifying cache in zookeeper without another thread making
intermediate modifications. These clients synchronize on the 'this' instance so no other has
access concurrently. Reads must be able to continue concurrently.</div>
