org.apache.hadoop.hbase.master.procedure.AbstractStateMachineTableProcedure<TState>

org.apache.hadoop.hbase.master.procedure.AbstractStateMachineRegionProcedure<TState>

所有已实现的接口:

Comparable<Procedure<MasterProcedureEnv>>, TableProcedureInterface

直接已知子类:

GCRegionProcedure, MoveRegionProcedure, SplitTableRegionProcedure

@InterfaceAudience.Private
public abstract class AbstractStateMachineRegionProcedure<TState>
extends AbstractStateMachineTableProcedure<TState>

Base class for all the Region procedures that want to use a StateMachine. It provides some basic helpers like basic locking, sync latch, and toStringClassDetails(). Defaults to holding the lock for the life of the procedure.

构造器详细资料

AbstractStateMachineRegionProcedure

public AbstractStateMachineRegionProcedure(MasterProcedureEnv env,
                                           RegionInfo hri)

AbstractStateMachineRegionProcedure

public AbstractStateMachineRegionProcedure()

方法详细资料

getRegion

protected RegionInfo getRegion()

返回:

The RegionInfo of the region we are operating on.

setRegion

protected void setRegion(RegionInfo hri)

Used when deserializing. Otherwise, DON'T TOUCH IT!

getTableName

public TableName getTableName()

指定者:

getTableName 在接口中 TableProcedureInterface

指定者:

getTableName 在类中 AbstractStateMachineTableProcedure<TState>

返回:

the name of the table the procedure is operating on

getTableOperationType

public abstract TableProcedureInterface.TableOperationType getTableOperationType()

从接口复制的说明: TableProcedureInterface

Given an operation type we can take decisions about what to do with pending operations. e.g. if we get a delete and we have some table operation pending (e.g. add column) we can abort those operations.

指定者:

getTableOperationType 在接口中 TableProcedureInterface

指定者:

getTableOperationType 在类中 AbstractStateMachineTableProcedure<TState>

返回:

the operation type that the procedure is executing.

toStringClassDetails

public void toStringClassDetails(StringBuilder sb)

覆盖:

toStringClassDetails 在类中 AbstractStateMachineTableProcedure<TState>

checkTableModifiable

protected void checkTableModifiable(MasterProcedureEnv env)
                             throws IOException

覆盖:

checkTableModifiable 在类中 AbstractStateMachineTableProcedure<TState>

参数:

env - MasterProcedureEnv

抛出:

IOException

protected boolean holdLock(MasterProcedureEnv env)

覆盖:

holdLock 在类中 Procedure<MasterProcedureEnv>

acquireLock

releaseLock

protected void releaseLock(MasterProcedureEnv env)

覆盖:

releaseLock 在类中 AbstractStateMachineTableProcedure<TState>

setFailure

protected void setFailure(Throwable cause)

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

覆盖:

serializeStateData 在类中 StateMachineProcedure<MasterProcedureEnv,TState>

抛出:

IOException

deserializeStateData

protected void deserializeStateData(ProcedureStateSerializer serializer)
                             throws IOException

覆盖:

deserializeStateData 在类中 StateMachineProcedure<MasterProcedureEnv,TState>

抛出:

IOException
