getTableName

public TableName getTableName()

Specified by:

getTableName in interface TableProcedureInterface

Specified by:

getTableName in class AbstractStateMachineTableProcedure<ModifyTableState>

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<ModifyTableState>

Returns:

the operation type that the procedure is executing.

releaseLock

protected void releaseLock(MasterProcedureEnv env)

Overrides:

releaseLock in class AbstractStateMachineTableProcedure<ModifyTableState>

holdLock

protected boolean holdLock(MasterProcedureEnv env)

hasLock

protected boolean hasLock(MasterProcedureEnv env)

acquireLock

protected LockState acquireLock(MasterProcedureEnv env)

Overrides:

acquireLock in class AbstractStateMachineTableProcedure<ModifyTableState>
