s.apache.org/jira/secure/attachment/12555103/121127-global-barrier-proc.pdf To implement a custom globally barriered procedure, user needs to extend two classes: {@link MasterProcedureManager} and {@link RegionServerProcedureManager}. Implementation of {@link MasterProcedureManager} is loaded into {@link HMaster} process via configurationparameter 'hbase.procedure.master.classes', while implementation of {@link RegionServerProcedureManager} is loaded into {@link HRegionServer} process viaconfiguration parameter 'hbase.procedure.regionserver.classes'. An example of globally barriered procedure implementation is {@link SnapshotManager} and{@link RegionServerSnapshotManager}. 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 {@link HMaster} and {@link HRegionServer} witch create the procedure znode and register thelisteners. A procedure can be triggered by its signature and an instant name (encapsulated in a {@link ProcedureDescription} object). When the servers are shutdown, the stop methods on bothclasses are called to clean up the data associated with the procedure.
