Hi @twalthr, thank you so much for looking into this. I'll create an issue
for functions with > 2 inputs.
I have replaced `createTypeInfo` with `getMapReturnTypes` where possible,
but I'm getting a test failure now that I can't figure out. Please see
`org.apache.flink.graph.scala.test.operations.GraphCreationWithCsvITCase#testCsvWithMapperValues`.
Am I using the `getMapReturnTypes` method properly?
