<div class="block">A life-cycle management interface for globally barriered procedures on master. See the following
doc on details of globally barriered procedure:
https://issues.apache.org/jira/secure/attachment/12555103/121127-global-barrier-proc.pdf To
implement a custom globally barriered procedure, user needs to extend two classes:
<a href="MasterProcedureManager.html" title="class in org.apache.hadoop.hbase.procedure"><code>MasterProcedureManager</code></a> and <a href="RegionServerProcedureManager.html" title="class in org.apache.hadoop.hbase.procedure"><code>RegionServerProcedureManager</code></a>. Implementation of
<a href="MasterProcedureManager.html" title="class in org.apache.hadoop.hbase.procedure"><code>MasterProcedureManager</code></a> is loaded into <a href="../master/HMaster.html" title="class in org.apache.hadoop.hbase.master"><code>HMaster</code></a>
process via configuration parameter 'hbase.procedure.master.classes', while implementation of
<a href="RegionServerProcedureManager.html" title="class in org.apache.hadoop.hbase.procedure"><code>RegionServerProcedureManager</code></a> is loaded into
<a href="../regionserver/HRegionServer.html" title="class in org.apache.hadoop.hbase.regionserver"><code>HRegionServer</code></a> process via configuration parameter
'hbase.procedure.regionserver.classes'. An example of globally barriered procedure implementation
is <a href="../master/snapshot/SnapshotManager.html" title="class in org.apache.hadoop.hbase.master.snapshot"><code>SnapshotManager</code></a> and
<a href="../regionserver/snapshot/RegionServerSnapshotManager.html" title="class in org.apache.hadoop.hbase.regionserver.snapshot"><code>RegionServerSnapshotManager</code></a>. A globally
barriered procedure is identified by its signature (usually it is the name of the procedure
znode). During the initialization phase, the initialize methods are called by both
<a href="../master/HMaster.html" title="class in org.apache.hadoop.hbase.master"><code>HMaster</code></a> and
<a href="../regionserver/HRegionServer.html" title="class in org.apache.hadoop.hbase.regionserver"><code>HRegionServer</code></a> which create the procedure znode and
register the listeners. A procedure can be triggered by its signature and an instant name
(encapsulated in a <code>HBaseProtos.ProcedureDescription</code> object). When the servers are shutdown, the stop
methods on both classes are called to clean up the data associated with the procedure.</div>
