>  TypeInformation getProducedType() {
>    return TypeExtractor.createTypeInfo(SourceFunction.class, this.getClass(), 0, null, null);
>  } 
> }
> DataStream ds = tEnv.addSource(new MySource(), Types.ROW(Types.STRING))
> {code}
> The returned {{TypeInformation}} of {{MySource}} is {{GenericTypeInfo}}, not the user given {{RowTypeInfo}}.
> It seems that {{StreamExecutionEnvironment#getTypeInfo}} doesn't use the user given {{typeInfo}} in the highest priority.
