    Thanks for the pull request!
    You did not convert all InputFormats and OutputFormats. There are a few more, e.g. HadoopInputFormatBase
or JDBCInputFormat. Other than that, your pull request looks good. I think it is fine to keep
the notion of normal and rich, just like we do for the operator user functions. That also
means that we do not break the existing interfaces.

>             Project: Flink
>          Issue Type: Improvement
>          Components: Local Runtime
>    Affects Versions: 0.9, 0.8.1
>            Reporter: Fabian Hueske
>            Priority: Minor
>             Fix For: 0.9
> User function that extend a RichFunction can access a {{RuntimeContext}} which gives
the parallel id of the task and access to Accumulators and BroadcastVariables. 
> Right now, Input and OutputFormats cannot access their {{RuntimeContext}}.
