@Private
public class SyncReplicationReplayWALProcedure
extends AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

The procedure for replaying a set of remote wals. It will get an available region server and schedule a SyncReplicationReplayWALRemoteProcedure to actually send the request to region server.

Method Details

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
 org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState state)
                                               throws ProcedureSuspendedException

Description copied from class: StateMachineProcedure

called to perform a single step of the specified 'state' of the procedure

Specified by:

executeFromState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

state - state to execute

Returns:

Flow.NO_MORE_STATE if the procedure is completed, Flow.HAS_MORE_STATE if there is another step.

Throws:

ProcedureSuspendedException

rollbackState

protected void rollbackState(MasterProcedureEnv env,
 org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState state)
                      throws IOException,
InterruptedException

Description copied from class: StateMachineProcedure

called to perform the rollback of the specified state

Overrides:

rollbackState in class AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

state - state to rollback

Throws:

IOException - temporary failure, the rollback will retry later

InterruptedException

getState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState getState(int state)

Description copied from class: StateMachineProcedure

Convert an ordinal (or state id) to an Enum (or more descriptive) state object.

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

Parameters:

state - the ordinal() of the state enum (or state id)

Returns:

the state enum object

getStateId

protected int getStateId(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState state)

Description copied from class: StateMachineProcedure

Convert the Enum (or more descriptive) state object to an ordinal (or state id).

Specified by:

getStateId in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

Parameters:

state - the state enum object

Returns:

stateId the ordinal() of the state enum (or state id)

getInitialState

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState getInitialState()

Description copied from class: StateMachineProcedure

Return the initial state object that will be used for the first call to executeFromState().

Specified by:

getInitialState in class StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

Returns:

the initial state enum object

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Description copied from class: Procedure

The user-level code of the procedure may have some state to persist (e.g. input arguments or current position in the processing state) to be able to resume on failure.

Overrides:

serializeStateData in class AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

Parameters:

serializer - stores the serializable state

Throws:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

Description copied from class: Procedure

Called on store load to allow the user to decode the previously serialized state.

Overrides:

deserializeStateData in class AbstractPeerNoLockProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.SyncReplicationReplayWALState>

Parameters:

serializer - contains the serialized state

Throws:

IOException

getPeerOperationType

public PeerProcedureInterface.PeerOperationType getPeerOperationType()

afterReplay

protected void afterReplay(MasterProcedureEnv env)

Description copied from class: Procedure

Called when the procedure is ready to be added to the queue after the loading/replay operation.

Overrides:

afterReplay in class Procedure<MasterProcedureEnv>
