org.apache.hadoop.hbase.master.assignment

类 RegionRemoteProcedureBase

java.lang.Object

org.apache.hadoop.hbase.procedure2.Procedure<MasterProcedureEnv>

org.apache.hadoop.hbase.master.assignment.RegionRemoteProcedureBase

所有已实现的接口:

Comparable<Procedure<MasterProcedureEnv>>, TableProcedureInterface, RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

直接已知子类:

CloseRegionProcedure, OpenRegionProcedure

@InterfaceAudience.Private
public abstract class RegionRemoteProcedureBase
extends Procedure<MasterProcedureEnv>
implements TableProcedureInterface, RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

The base class for the remote procedures used to open/close a region.

Notice that here we do not care about the result of the remote call, if the remote call is finished, either succeeded or not, we will always finish the procedure. The parent procedure should take care of the result and try to reschedule if the result is not good.
