The problem is probably this dependency:
org.apache.kafka
kafka_2.9.1
0.8.2.0
Since it pulls Scala 2.9. You can probably remove this dependency because our
kafka connector will also pull also that kafka dependency.

Hi!
You actually don't need an extra Akka or Scala dependency.
My suspicion is that you have still some incorrect artifact in the
dependencies. Good thing is that these problems disappear when you can
reference a stable release.
Is it possible for you to share the complete dependency section of your project?
Thanks,
Stephan

Do I need to include any specific Scala or Akka dependency?

Hi!
You are using some outdated dependencies. Now, all Scala-dependent Flink
artifacts include the Scala Version Suffix (following common conventions)
Please substitute:
- flink-streaming-java--> flink-streaming-java_2.10
- flink-clients --> flink-clients_2.10
- flink-connector-kafka --> flink-connector-kafka-0.8_2.10
That should do it.
FYI: You can also try to use the latest release candidate, described here:
