protected boolean |
abort(MasterProcedureEnv env)
The abort() call is asynchronous and each procedure must decide how to deal
with it, if they want to be abortable.

protected void |
deserializeStateData(ProcedureStateSerializer serializer)
Called on store load to allow the user to decode the previously serialized
state.

remoteCallBuild(MasterProcedureEnv env,
ServerName remote)
For building the remote operation.
|
protected void |
rollback(MasterProcedureEnv env)
The code to undo what was done by the execute() code.
|
protected void |
serializeStateData(ProcedureStateSerializer serializer)
The user-level code of the procedure may have some state to
persist (e.g.

protected boolean |

The
Procedure.doAcquireLock(Object, ProcedureStore) will be split into two steps, first, it will
call us to determine whether we need to wait for initialization, second, it will call
Procedure.acquireLock(Object) to actually handle the lock for this procedure. |

ProcedureNOTE: abort() is not like Thread.interrupt(). It is just a notification that allows the procedure implementor abort.

ProcedureProcedure.doAcquireLock(Object, ProcedureStore) will be split into two steps, first, it will
call us to determine whether we need to wait for initialization, second, it will call
Procedure.acquireLock(Object) to actually handle the lock for this procedure.
This is because that when master restarts, we need to restore the lock state for all the
procedures to not break the semantic if Procedure.holdLock(Object) is true. But the
ProcedureExecutor will be started before the master finish initialization(as it is part
of the initialization!), so we need to split the code into two steps, and when restore, we just
restore the lock part and ignore the waitInitialized part. Otherwise there will be dead lock.waitInitialized in class Procedure<MasterProcedureEnv>protected void serializeStateData(ProcedureStateSerializer serializer) throws IOException
