Github user r-pogalz commented on the pull request: https://github.com/apache/flink/pull/907#issuecomment-127293419 Hello @fhueske, I see you noticed that we replaced all occurrences of `Record` by `Tuple2<Integer, String>` in the InnerJoin- and OuterJoinITCases. The issue is that we did not yet adapt the other tests (~15 test classes) using the `TestData.Generator`. That's why we currently added a second Generator (`TestData.TupleGenerator`) for our purposes without the usage of `Record`. But I think it would be good to replace the old `TestData.Generator` by the new one and adapt all usages at some point in the future.
