-----------------------------------------------------------------
Any ExecutionEnvironment exctracts type from TypeExtractor by first element in
collection in such methods {{#fromCollection(Collection<X> data)}},
{{#fromElements(X... data)}}
I think we need rework them either or just don't use them with {{Row}} to
generate {{DataSet}}/{{DataStream}}
[~fhueske], [~jark] what do you think?
