方法详细资料

prePeerModification

protected abstract void prePeerModification(MasterProcedureEnv env)
                                     throws IOException,
                                            ReplicationException

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.

抛出:

IOException

ReplicationException

updatePeerStorage

protected abstract void updatePeerStorage(MasterProcedureEnv env)
                                   throws ReplicationException

抛出:

ReplicationException

postPeerModification

protected abstract void postPeerModification(MasterProcedureEnv env)
                                      throws IOException,
                                             ReplicationException

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.

抛出:

IOException

ReplicationException

nextStateAfterRefresh

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

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

enablePeerBeforeFinish

protected boolean enablePeerBeforeFinish()

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

getOldPeerConfig

protected ReplicationPeerConfig getOldPeerConfig()

getNewPeerConfig

protected ReplicationPeerConfig getNewPeerConfig()

updateLastPushedSequenceIdForSerialPeer

protected void updateLastPushedSequenceIdForSerialPeer(MasterProcedureEnv env)

                                                       ReplicationException

抛出:

IOException

ReplicationException

reopenRegions

protected void reopenRegions(MasterProcedureEnv env)
                      throws IOException

抛出:

IOException

enablePeer

protected void enablePeer(MasterProcedureEnv env)
                   throws ReplicationException

抛出:

                                             ReplicationException

抛出:

IOException

ReplicationException

setLastPushedSequenceIdForTable

protected final void setLastPushedSequenceIdForTable(MasterProcedureEnv env,
                                                     TableName tableName,
                                                     Map<String,Long> lastSeqIds)
                                              throws IOException,
                                                     ReplicationException
