Hi there, since I'm relying on Scala 2.11.4 on a project I've been working on, I created a branch which updates the Scala version used by Flink from 2.10.4 to 2.11.4:
https://github.com/stratosphere/flink/commits/scala_2.11 Everything seems to work fine and the PR contains minor changes compared to Spark: https://issues.apache.org/jira/browse/SPARK-4466 If you're interested, I can rewrite this as a Maven Profile and open a PR so people can build Flink with 2.11 support. I suggest to do this sooner rather than later in order to * the number of code changes enforced by migration small and tractable; * discourage the use of deprecated or 2.11-incompatible source code in future commits; Regards, A.
