UpdatePeerConfigProcedure

UpdatePeerConfigProcedure

public UpdatePeerConfigProcedure(String peerId,
                                 ReplicationPeerConfig peerConfig)

方法详细资料

getPeerOperationType

public PeerProcedureInterface.PeerOperationType getPeerOperationType()

nextStateAfterRefresh

protected org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerModificationState nextStateAfterRefresh()

从类复制的说明: ModifyPeerProcedure

Implementation class can override this method. By default we will jump to POST_PEER_MODIFICATION and finish the procedure.

覆盖:

nextStateAfterRefresh 在类中 ModifyPeerProcedure

updateLastPushedSequenceIdForSerialPeer

protected void updateLastPushedSequenceIdForSerialPeer(MasterProcedureEnv env)
                                                throws IOException,
                                                       ReplicationException

覆盖:

updateLastPushedSequenceIdForSerialPeer 在类中 ModifyPeerProcedure

抛出:

IOException

ReplicationException

enablePeerBeforeFinish

protected boolean enablePeerBeforeFinish()

从类复制的说明: ModifyPeerProcedure

The implementation class should override this method if the procedure may enter the serial related states.

覆盖:

enablePeerBeforeFinish 在类中 ModifyPeerProcedure

getOldPeerConfig

protected ReplicationPeerConfig getOldPeerConfig()

覆盖:

getOldPeerConfig 在类中 ModifyPeerProcedure

getNewPeerConfig

protected ReplicationPeerConfig getNewPeerConfig()

覆盖:

getNewPeerConfig 在类中 ModifyPeerProcedure

prePeerModification

protected void prePeerModification(MasterProcedureEnv env)
                            throws IOException

从类复制的说明: ModifyPeerProcedure

Called before we start the actual processing. The implementation should call the pre CP hook, and also the pre-check for the peer modification.

If an IOException is thrown then we will give up and mark the procedure as failed directly. If all checks passes then the procedure can not be rolled back any more.

指定者:

prePeerModification 在类中 ModifyPeerProcedure

抛出:

IOException

updatePeerStorage

protected void updatePeerStorage(MasterProcedureEnv env)
                          throws ReplicationException

指定者:

updatePeerStorage 在类中 ModifyPeerProcedure

抛出:

ReplicationException

postPeerModification

protected void postPeerModification(MasterProcedureEnv env)
                             throws IOException,
                                    ReplicationException

从类复制的说明: ModifyPeerProcedure

Called before we finish the procedure. The implementation can do some logging work, and also call the coprocessor hook if any.

Notice that, since we have already done the actual work, throwing IOException here will not fail this procedure, we will just ignore it and finish the procedure as suceeded. If ReplicationException is thrown we will retry since this usually means we fails to update the peer storage.

指定者:

postPeerModification 在类中 ModifyPeerProcedure

抛出:

IOException

ReplicationException

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

覆盖:

serializeStateData 在类中 AbstractPeerProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerModificationState>

抛出:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

覆盖:

deserializeStateData 在类中 AbstractPeerProcedure<org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.PeerModificationState>

抛出:

IOException
