I just tried using `TypeSerializerOutputFormat` for a DataSet sink. There
is no error. The system only creates an empty file. How can I force the usage
of a file-channel (instead of network or in-memory chaining) between two
mappers?

> 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.
