java.lang.Object

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

org.apache.hadoop.hbase.procedure2.StateMachineProcedure<MasterProcedureEnv,TState>

org.apache.hadoop.hbase.master.replication.AbstractPeerNoLockProcedure<TState>

All Implemented Interfaces:

Comparable<Procedure<MasterProcedureEnv>>, PeerProcedureInterface

Direct Known Subclasses:

AbstractPeerProcedure, RecoverStandbyProcedure, SyncReplicationReplayWALProcedure

@InterfaceAudience.Private
public abstract class AbstractPeerNoLockProcedure<TState>
extends StateMachineProcedure<MasterProcedureEnv,TState>
implements PeerProcedureInterface

Base class for replication peer related procedures which do not need to hold locks(for most of the sub procedures).
