Why did you pick Scala/Java for your project?

[Julio Biason]

Hey guys,

We are in a point when we are almost good to go with our pipeline in Flink, but when building it, we found a bunch of problems with the docs about the Scala API (the mail I sent a few days ago was one of the many documentation problems I found so far).

So, we are kinda wondering: Why each of you picked Scala or Java for your projects? Were there any reasons beyond "We know it"?

(Sorry if the question is too broad and open but the team is really divided about this question and we can pick enough points on the internet about Scala vs Java, but we really want to hear about the people _building_ Flink stuff.)
