protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
                                          org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState state)
                                               throws InterruptedException

指定者:

rollbackState 在类中 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState>

抛出:

IOException

getState

protected org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState getState(int stateId)

指定者:

getState 在类中 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState>

getStateId

protected int getStateId(org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState state)

指定者:

getStateId 在类中 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState>

覆盖:

setNextState 在类中 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState>

abort

public boolean abort(MasterProcedureEnv env)

指定者:

abort 在类中 Procedure<MasterProcedureEnv>

serializeStateData

public void serializeStateData(OutputStream stream)
                        throws IOException

覆盖:

serializeStateData 在类中 StateMachineProcedure<MasterProcedureEnv,org.apache.hadoop.hbase.protobuf.generated.MasterProcedureProtos.DeleteNamespaceState>

抛出:

IOException

deserializeStateData

public void deserializeStateData(InputStream stream)
                          throws IOException

覆盖:

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 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.
