getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<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<EnableTableState>

Returns:

the operation type that the procedure is executing.

setTableStateToEnabling

protected static void setTableStateToEnabling(MasterProcedureEnv env,
                                              TableName tableName)
                                       throws java.io.IOException

Mark table state to Enabling

Parameters:

env - MasterProcedureEnv

tableName - the target table

Throws:

java.io.IOException

setTableStateToEnabled

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

Mark table state to Enabled

Parameters:

env - MasterProcedureEnv

Throws:

java.io.IOException
