I updated this JIRA to fix the {{crossWith}} hints in the Java and Scala API.

>                 Key: FLINK-333
>                 URL: https://issues.apache.org/jira/browse/FLINK-333
>             Project: Flink
>          Issue Type: Bug
>          Components: Java API, Optimizer, Scala API
>    Affects Versions: 0.6.1-incubating, 0.7-incubating
>            Reporter: Fabian Hueske
>            Assignee: Aljoscha Krettek
>            Priority: Critical
>             Fix For: pre-apache
> The Java and the Scala API offer {{crossWithHuge()}} and {{crossWithTiny()}} API methods
that allow the user to give hints to the optimizer about the size of the inputs a cross.
> However, these hints are not considered and all {{cross}} transformations are handled
the same by the optimizer. 
> Similiar hints for Join exist and are implemented correctly.
