rheem-api-scala-java's Issues

Issue with joining records

It seems that there is an issue with joining two RecordsDataQuantaBuilder. I did something like this:

JoinDataQuantaBuilder<Record, Record, Object> joinedRecords = sAndC
                 .join(record -> record.getField(0), sAndP, record -> record.getField(0));

Here is the stack trace:

Exception in thread "main" java.lang.IllegalArgumentException: Cannot connect out@Map[1->1, id=e7edb54] of DataSetType[RecordType[s, o]] to in1@Join[2->1, id=378542de] of type DataSetType[BasicDataUnitType[Void]].

I have been able to pinpoint the issue, it is in this part where it gets void

Line 1300 in b8ed82f

inputDataQuanta0.dataQuanta().joinJava(keyUdf0, inputDataQuanta1.dataQuanta(), keyUdf1)(inputDataQuanta1.classTag, this.keyTag)
