@InterfaceAudience.Private
public class SplitWALRemoteProcedure
extends ServerRemoteProcedure
implements ServerProcedureInterface

A remote procedure which is used to send split WAL request to region server. it will return null if the task is succeed or return a DoNotRetryIOException SplitWALProcedure will help handle the situation that encounter DoNotRetryIOException. Otherwise it will retry until succeed.

                               ServerName crashedServer,
                               String wal)

方法详细资料

rollback

protected void rollback(MasterProcedureEnv env)
                 throws IOException,
                        InterruptedException

指定者:

rollback 在类中 Procedure<MasterProcedureEnv>

抛出:

IOException

InterruptedException

abort

protected boolean abort(MasterProcedureEnv env)

指定者:

abort 在类中 Procedure<MasterProcedureEnv>

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

指定者:

serializeStateData 在类中 Procedure<MasterProcedureEnv>

抛出:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

指定者:

deserializeStateData 在类中 Procedure<MasterProcedureEnv>

抛出:

IOException

remoteCallBuild

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

指定者:

remoteCallBuild 在接口中 RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

complete

protected void complete(MasterProcedureEnv env,
                        Throwable error)

指定者:

complete 在类中 ServerRemoteProcedure

getWAL

public String getWAL()

getServerName

public ServerName getServerName()

指定者:

getServerName 在接口中 ServerProcedureInterface

返回:

Name of this server instance.

hasMetaTableRegion

public boolean hasMetaTableRegion()

指定者:

hasMetaTableRegion 在接口中 ServerProcedureInterface

返回:

True if this server has an hbase:meta table region.

getServerOperationType

public ServerProcedureInterface.ServerOperationType getServerOperationType()

从接口复制的说明: ServerProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a crash handler and we have some assignment operation pending we can abort those operations.

指定者:

getServerOperationType 在接口中 ServerProcedureInterface

返回:

the operation type that the procedure is executing.
