-----------------------------------
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.
