    Hi @tillrohrmann, thanks for your review and comments. I will work through it soon. 
    
    Regarding the ticket FLINK-2106, @fhueske suggested us to create multiple PRs for runtime,
optimizer and API integration. I guess it is an unusual way, but is it possible to have more
than one PR for an issue? If not, I will change the description of FLINK-2106 as you said
and create two more tasks for the optimizer and API part.

> Add left/right/full outer join methods to the DataSet APIs (Java, Scala), to the optimizer,
and the runtime of Flink.
> Initially, the execution strategy should be a sort-merge outer join (FLINK-2105) but
can later be extended to hash joins for left/right outer joins.
