No worries :-)
You better use a dedicated branch for your next PR instead of the master
branch.
I'll go ahead and merge this PR now. Thanks for the contribution!
> Improve distinct() transformation
> ---------------------------------
>
> Key: FLINK-1963
> URL: https://issues.apache.org/jira/browse/FLINK-1963
> Project: Flink
> Issue Type: Improvement
> Components: Java API, Scala API
> Affects Versions: 0.9
> Reporter: Fabian Hueske
> Assignee: pietro pinoli
> Priority: Minor
> Labels: starter
> Fix For: 0.9
>
>
> The `distinct()` transformation is a bit limited right now with respect to
> processing atomic key types:
> - `distinct(String ...)` works only for composite data types (POJO, tuple),
> but wildcard expression should also be supported for atomic key types
> - `distinct()` only works for composite types, but should also work for
> atomic key types
> - `distinct(KeySelector)` is the most generic one, but not very handy to use
> - `distinct(int ...)` works only for Tuple data types (which is fine)
> Fixing this should be rather easy.
