>             Project: Flink
>          Issue Type: Bug
>          Components: DataSet API, DataStream API
>    Affects Versions: 1.1.3
>            Reporter: radu
>            Priority: Minor
>              Labels: features

> Using the "returns" option from the API in order to enforce the type for the data stream will lead create incorrect types for java.sql.* types. The TypeInfoParser, used to parse the types, needs to be extended to parse the java.sql.* types into the corresponding TypeInfos.
>  
> Example
> = ds.map(new mapFunction(){
>     ...           
> }}) .returns(“Tuple#<java.sql.TIMESTAMP,…>”);
>  
>  
> The problem is that if you rely on the type extraction mechanism called within the "returns()" to recognize TIMESTAMP of type SqlTimeTypeInfo it will not happen but instead a GenericType<TIMESTAMP> will be created. It is the same for the other sql types (e.g. TIME)
