Class SplitWALRemoteProcedure

java.lang.Object

org.apache.hadoop.hbase.procedure2.Procedure<MasterProcedureEnv>

org.apache.hadoop.hbase.master.procedure.ServerRemoteProcedure

org.apache.hadoop.hbase.master.procedure.SplitWALRemoteProcedure

All Implemented Interfaces:

Comparable<Procedure<MasterProcedureEnv>>, ServerProcedureInterface, RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

@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 succeeded or return a DoNotRetryIOException. SplitWALProcedure will help handle the situation that encounters DoNotRetryIOException. Otherwise it will retry until success.

protected boolean abort(MasterProcedureEnv env)

Specified by:

abort in class Procedure<MasterProcedureEnv>

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Specified by:

serializeStateData in class Procedure<MasterProcedureEnv>

Throws:

remoteCallBuild

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

Specified by:

remoteCallBuild in interface RemoteProcedureDispatcher.RemoteProcedure<MasterProcedureEnv,ServerName>

complete

Specified by:

complete in class ServerRemoteProcedure

getWAL

public String getWAL()

getServerName

public ServerName getServerName()

Specified by:

getServerName in interface ServerProcedureInterface

Returns:

Name of this server instance.

hasMetaTableRegion

public boolean hasMetaTableRegion()

Specified by:

hasMetaTableRegion in interface ServerProcedureInterface

Returns:

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

getServerOperationType

public ServerProcedureInterface.ServerOperationType getServerOperationType()

Description copied from interface: 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.

Specified by:

getServerOperationType in interface ServerProcedureInterface

Returns:

the operation type that the procedure is executing.

toStringClassDetails

protected void toStringClassDetails(StringBuilder builder)

Overrides:

toStringClassDetails in class Procedure<MasterProcedureEnv>

getProcName

public String getProcName()

Overrides:

getProcName in class Procedure<MasterProcedureEnv>
