--------------------------------------
Good catch!
I don't see a reason not change that.
> setCombinable() clunky to use
> -----------------------------
>
> Key: FLINK-1244
> URL: https://issues.apache.org/jira/browse/FLINK-1244
> Project: Flink
> Issue Type: Wish
> Components: Java API
> Affects Versions: 0.7.0-incubating
> Reporter: Chesnay Schepler
> Priority: Trivial
> Labels: starter
>
> Setting the combinable property for a GroupReduce manually is a bit clunky,
> since setCombinable() doesn't return the operator.
> A wordcount would look like this:
> {code:java}
> GroupReduceOperator output = source
> .map...
> .groupBy(1)
> .reduceGroup...;
> output.setCombinable(true);
> output.print();
> {code}
> whereas this would be more convenient
> {code:java}
> source
> .map...
> .groupBy(1)
> .reduceGroup...
> .setCombinale(true)
> .print();
> {code}
> is there a reason for it not returning the operator?
