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

Thanks Stephan. I am using the new dependencies from the 1.0.0 release
candidate.
Now, my application is failing with the below error,
java.lang.NoClassDefFoundError: scala/concurrent/ExecutionContext
The error is here,
https://github.com/apache/flink/blob/b54499b1cf6d14d01e448ea9ce8edabaaba83929/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/environment/LocalStreamEnvironment.java#L104
Do I need to include any specific Scala or Akka dependency?
Thanks,

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You are using some outdated dependencies.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:
http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/VOTE-Release-Apache-Flink-1-0-0-RC5-td10628.html

Hey All,

I checked the Flink source and couldn’t find the
org.apache.flink.api.java.operators.Keys class.
I found org.apache.flink.api.common.operators.Keys instead. Is there any other
Flink dependency which I am missing?
Thanks,
Naveen
