Method Detail

executeFromState

protected StateMachineProcedure.Flow executeFromState(MasterProcedureEnv env,
                                                      MasterProcedureProtos.EnableTableState state)
                                               throws InterruptedException

Specified by:

executeFromState in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

Throws:

InterruptedException

                             MasterProcedureProtos.EnableTableState state)
                      throws IOException

Specified by:

rollbackState in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

Throws:

IOException

isRollbackSupported

protected boolean isRollbackSupported(MasterProcedureProtos.EnableTableState state)

Overrides:

isRollbackSupported in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

getState

protected MasterProcedureProtos.EnableTableState getState(int stateId)

Specified by:

getState in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

getStateId

protected int getStateId(MasterProcedureProtos.EnableTableState state)

Specified by:

getStateId in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

getInitialState

protected MasterProcedureProtos.EnableTableState getInitialState()

Specified by:

getInitialState in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws IOException

Overrides:

serializeStateData in class StateMachineProcedure<MasterProcedureEnv,MasterProcedureProtos.EnableTableState>

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<MasterProcedureProtos.EnableTableState>

Returns:

the name of the table the procedure is operating on

getTableOperationType

public TableProcedureInterface.TableOperationType getTableOperationType()

Description copied from interface: 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.

Specified by:

getTableOperationType in interface TableProcedureInterface

Specified by:

getTableOperationType in class AbstractStateMachineTableProcedure<MasterProcedureProtos.EnableTableState>

Returns:

the operation type that the procedure is executing.

setTableStateToEnabling

                                              TableName tableName)
                                       throws IOException

Mark table state to Enabling

Parameters:

env - MasterProcedureEnv

tableName - the target table

Throws:

IOException

setTableStateToEnabled

protected static void setTableStateToEnabled(MasterProcedureEnv env,
                                             TableName tableName)
                                      throws IOException

Mark table state to Enabled

Parameters:
