Hi, Thanks for your reply, but I am still a bit confuse.
I have downloaded flink-0.10.1-bin-hadoop27-scala_2.11.tgz and kafka_2.11-0.9.0.0.tgz I did not install myself Scala Now tell me if I understand correctly. Depending on the version of Flink I have (in my case the scala 2.11) I must specify a dependency in the pom file But still have the same error Here's an extract of my file <dependencies> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-java</artifactId> <version>${flink.version}</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-clients</artifactId> <version>${flink.version}</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-connector-kafka</artifactId> <version>0.10.1</version> </dependency> <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-streaming-java_2.11</artifactId> <version>0.10.1</version> </dependency> </dependencies> -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Simple-Flink-Kafka-Test-tp4828p4850.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
