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

Base class for all the Table procedures that want to use a StateMachineProcedure. It provides helpers like basic locking, sync latch, and toStringClassDetails().

构造器详细资料

AbstractStateMachineTableProcedure

protected AbstractStateMachineTableProcedure()

AbstractStateMachineTableProcedure

protected AbstractStateMachineTableProcedure(MasterProcedureEnv env)

AbstractStateMachineTableProcedure

protected AbstractStateMachineTableProcedure(MasterProcedureEnv env,
                                             ProcedurePrepareLatch latch)

参数:

env - Uses this to set Procedure Owner at least.

方法详细资料

getTableName

public abstract 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>

getUser

protected User getUser()

setUser

protected void setUser(User user)

releaseSyncLatch

protected void releaseSyncLatch()

checkTableModifiable

protected void checkTableModifiable(MasterProcedureEnv env)
                             throws IOException

Check whether a table is modifiable - exists and either offline or online with config set

参数:

env - MasterProcedureEnv

抛出:

IOException

getWALRegionDir

protected final org.apache.hadoop.fs.Path getWALRegionDir(MasterProcedureEnv env,
                                                          RegionInfo region)
                                                   throws IOException

抛出:

IOException

preflightChecks

protected void preflightChecks(MasterProcedureEnv env,
                               Boolean enabled)
                        throws HBaseIOException

Check that cluster is up and master is running. Check table is modifiable. If enabled, check table is enabled else check it is disabled. Call in Procedure constructor so can pass any exception to caller.

参数:

enabled - If true, check table is enabled and throw exception if not. If false, do the inverse. If null, do no table checks.

抛出:

HBaseIOException

checkOnline

protected static void checkOnline(MasterProcedureEnv env,
                                  RegionInfo ri)
                           throws DoNotRetryRegionException

Check region is online.

抛出:

DoNotRetryRegionException
