类 AbstractStateMachineNamespaceProcedure<TState>

java.lang.Object

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

org.apache.hadoop.hbase.procedure2.StateMachineProcedure<MasterProcedureEnv,TState>

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

所有已实现的接口:

Comparable<Procedure<MasterProcedureEnv>>, TableProcedureInterface

直接已知子类:

CreateNamespaceProcedure, DeleteNamespaceProcedure, ModifyNamespaceProcedure

@InterfaceAudience.Private
public abstract class AbstractStateMachineNamespaceProcedure<TState>
extends StateMachineProcedure<MasterProcedureEnv,TState>
implements TableProcedureInterface

Base class for all the Namespace procedures that want to use a StateMachineProcedure. It provide some basic helpers like basic locking and basic toStringClassDetails().

方法详细资料

getNamespaceName

protected abstract String getNamespaceName()

getTableName

public TableName getTableName()

指定者:

getTableName 在接口中 TableProcedureInterface

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

返回:

the operation type that the procedure is executing.

toStringClassDetails

public void toStringClassDetails(StringBuilder sb)

覆盖:

toStringClassDetails 在类中 Procedure<MasterProcedureEnv>

waitInitialized

protected boolean waitInitialized(MasterProcedureEnv env)

覆盖:

waitInitialized 在类中 Procedure<MasterProcedureEnv>

acquireLock

protected Procedure.LockState acquireLock(MasterProcedureEnv env)

覆盖:

acquireLock 在类中 Procedure<MasterProcedureEnv>

releaseLock

protected void releaseLock(MasterProcedureEnv env)

覆盖:

releaseLock 在类中 Procedure<MasterProcedureEnv>

releaseSyncLatch

protected void releaseSyncLatch()
