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

             Summary: There's a mistake in the comments of CoGroupedStreams.java
                 Key: FLINK-10000
                 URL: https://issues.apache.org/jira/browse/FLINK-10000
             Project: Flink
          Issue Type: Improvement
          Components: DataStream API
            Reporter: Shimin Yang
            Assignee: Shimin Yang


The example of CoGroupedStream 

  * DataStream<T> result = one.coGroup(two)
 *     .where(new MyFirstKeySelector())
 *     .equalTo(new MyFirstKeySelector())
 *     .window(TumblingEventTimeWindows.of(Time.of(5, TimeUnit.SECONDS)))
 *     .apply(new MyCoGroupFunction());
 * } </pre>

the params of method equalTo should be MySecondKeySelector instead of MyFirstKeySelector.
