remoteCallBuild

public abstract Optional<RemoteProcedureDispatcher.RemoteOperation> remoteCallBuild(MasterProcedureEnv env,
                                                                                    ServerName serverName)

Deprecated.

Description copied from interface: RemoteProcedureDispatcher.RemoteProcedure

For building the remote operation. May be empty if no need to send remote call. Usually, this means the RemoteProcedure has been finished already. This is possible, as we may have already sent the procedure to RS but then the rpc connection is broken so the executeProcedures call fails, but the RS does receive the procedure and execute it and then report back, before we retry again.

Specified by:

remoteCallBuild in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

remoteCallFailed

protected abstract boolean remoteCallFailed(MasterProcedureEnv env,
                                            RegionStateNode regionNode,
                                            IOException exception)

Deprecated.

remoteCallFailed

public void remoteCallFailed(MasterProcedureEnv env,
                             ServerName serverName,
                             IOException exception)

Deprecated.

Description copied from interface: RemoteProcedureDispatcher.RemoteProcedure

Called when the executeProcedure call is failed.

Specified by:

remoteCallFailed in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

toStringState

protected void toStringState(StringBuilder builder)

Deprecated.

Description copied from class: Procedure

Called from Procedure.toString() when interpolating Procedure State. Allows decorating generic Procedure State with Procedure particulars.

Overrides:

toStringState in class Procedure<MasterProcedureEnv>

Parameters:

builder - Append current ProcedureProtos.ProcedureState

execute

protected Procedure[] execute(MasterProcedureEnv env)

Deprecated.

Description copied from class: Procedure

The main code of the procedure. It must be idempotent since execute() may be called multiple times in case of machine failure in the middle of the execution.

Specified by:

execute in class Procedure<MasterProcedureEnv>

Parameters:

env - the environment passed to the ProcedureExecutor

Returns:

a set of sub-procedures to run or ourselves if there is more work to do or null if the procedure is done.

rollback

protected void rollback(MasterProcedureEnv env)

Deprecated.

Description copied from class: Procedure

The code to undo what was done by the execute() code. It is called when the procedure or one of the sub-procedures failed or an abort was requested. It should cleanup all the resources created by the execute() call. The implementation must be idempotent since rollback() may be called multiple time in case of machine failure in the middle of the execution.

Specified by:

rollback in class Procedure<MasterProcedureEnv>

Parameters:

env - the environment passed to the ProcedureExecutor

isRollbackSupported

protected abstract boolean isRollbackSupported(org.apache.hadoop.hbase.shaded.protobuf.generated.MasterProcedureProtos.RegionTransitionState state)

Deprecated.

abort

protected boolean abort(MasterProcedureEnv env)

Deprecated.

Description copied from class: Procedure

The abort() call is asynchronous and each procedure must decide how to deal with it, if they want to be abortable. The simplest implementation is to have an AtomicBoolean set in the abort() method and then the execute() will check if the abort flag is set or not. abort() may be called multiple times from the client, so the implementation must be idempotent.

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

Specified by:

abort in class Procedure<MasterProcedureEnv>

remoteOperationCompleted

public void remoteOperationCompleted(MasterProcedureEnv env)

Deprecated.

Description copied from interface: RemoteProcedureDispatcher.RemoteProcedure

Called when RS tells the remote procedure is succeeded through the reportProcedureDone method.

Specified by:

remoteOperationCompleted in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

remoteOperationFailed

public void remoteOperationFailed(MasterProcedureEnv env,
                                  RemoteProcedureException error)

Deprecated.

Description copied from interface: RemoteProcedureDispatcher.RemoteProcedure

Called when RS tells the remote procedure is failed through the reportProcedureDone method.

Specified by:

remoteOperationFailed in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>
