Project: Flink
Issue Type: Bug
Affects Versions: 1.6.3, 1.7.0
Reporter: Piotr Nowojski
Currently there are couple of places which reference Scala 2.10 in our code
base:
{noformat}
git grep "2\.10" | grep -i scala

scala 2.10. This connector supports <a

transactional messaging</a> to provide exactly once semantic for the
producer.</td>
