isRollbackSupported

protected boolean isRollbackSupported(DisableTableState state)

getState

protected DisableTableState getState(int stateId)

getStateId

protected int getStateId(DisableTableState state)

getInitialState

protected DisableTableState getInitialState()

serializeStateData

protected void serializeStateData(ProcedureStateSerializer serializer)
                           throws java.io.IOException

getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<DisableTableState>

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<DisableTableState>

Returns:

the operation type that the procedure is executing.

preDisable

protected void preDisable(MasterProcedureEnv env,
                          DisableTableState state)
                   throws java.io.IOException,
                          java.lang.InterruptedException

Action before disabling table.

Parameters:

env - MasterProcedureEnv

state - the procedure state

Throws:

java.io.IOException

java.lang.InterruptedException

setTableStateToDisabling

                                        throws java.io.IOException

Mark table state to Disabling

Parameters:
