| Modifier and Type | Method and Description |
|---|---|
protected void |
deserializeStateData(ProcedureStateSerializer serializer)
Called on store load to allow the user to decode the previously serialized
state.
|
protected boolean |
enablePeerBeforeFinish()
The implementation class should override this method if the procedure may enter the serial
related states.

getOldPeerConfig() |
PeerProcedureInterface.PeerOperationType |
getPeerOperationType() |
protected MasterProcedureProtos.PeerModificationState |
nextStateAfterRefresh()
Implementation class can override this method.
|
protected void |
postPeerModification(MasterProcedureEnv env)
Called before we finish the procedure.
|
protected void |
prePeerModification(MasterProcedureEnv env)
Called before we start the actual processing.
|
protected void |
serializeStateData(ProcedureStateSerializer serializer)
The user-level code of the procedure may have some state to
persist (e.g.

ModifyPeerProcedureIf 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.

ModifyPeerProcedure
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.
