Your are right Tuple0 support for the TupleGenerator is not important.
Actually, I meant the change of `import java.util.LinkedList;` to `import
java.util.ArrayList;` otherwise these changes get lost if the TupleGenerator is
executed.
> Integrate Tuple0

> Key: FLINK-2457
> URL: https://issues.apache.org/jira/browse/FLINK-2457
> Project: Flink
> Issue Type: Improvement
> Reporter: Matthias J. Sax
> Assignee: Matthias J. Sax
> Priority: Minor
>
> Tuple0 is not cleanly integrated:
> - missing serialization/deserialization support in runtime
> - Tuple.getTupleClass(int arity) cannot handle arity zero, ie, cannot create
> an instance of Tuple0
> Tuple0 is currently only used in Python API, but will be integrated into
> Storm compatibility, too.
