> I think it would be more readable and user-friendly to have a DataSet.distinct() operator instead of manually use e.g. for Tuple5:
> ```java
> DataSet.groupBy(0,1,2,3,4).reduceGroup(new GroupReduceFunction<...>() {
> 	private static final long serialVersionUID = 1L;
> 	@Override
> 	public void reduce(Iterator<...> values, Collector<...> out) throws Exception {
> 		out.collect(values.next());						
> 	}					
> });
> ```
