---------------------------

             Summary: TypeInfoParser needs to be extended to parse the java.sql.* types into the corresponding TypeInfos.
                 Key: FLINK-4969
                 URL: https://issues.apache.org/jira/browse/FLINK-4969
             Project: Flink
          Issue Type: Bug
          Components: DataSet API, DataStream API
    Affects Versions: 1.1.3
            Reporter: radu
            Priority: Minor


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)
