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?

You are using some outdated dependencies.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 Greetings, Stephan On Thu, Mar 3, 2016 at 10:01 PM, Madhire, Naveen <naveen.madh...@capitalone.com<mailto:naveen.madh...@capitalone.com>> wrote: Hey All, I am getting the below error while executing a simple Kafka-Flink Application. java.lang.NoClassDefFoundError: org/apache/flink/api/java/operators/Keys Below are the maven dependencies which I included in my application. <dependency> <groupId>org.apache.kafka</groupId> <artifactId>kafka_2.9.1</artifactId> <version>0.8.2.0</version> </dependency> <dependency> <groupId>commons-configuration</groupId> <artifactId>commons-configuration</artifactId> <version>1.10</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-connector-kafka</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-java</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-clients</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-streaming-java</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> </dependency> 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?
