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?
