Re: error in using kafka in flink
Hello Thank you very much, but I imported "FlinkKafkaProducer09" and changed "FlinkKafkaProducer08" to it. Then problem solved.

Re: error in using kafka in flink
Hi Marzieh, This is because of a mismatch between your Kafka version and the one your job assumes (0.8). You should use an older Kafka version (0.8) for the job to run out-of-the-box or update your job to use FlinkKafkaProducer011.

error in using kafka in flink
Hello I downloaded kafka and followed these instructions step by step: cd kafka_2.11-2 # start zookeeper server ./bin/zookeeper-server-start.sh ./config/zookeeper.properties # start broker ./bin/kafka-server-start.sh ./config/server.properties # create topic “test” ./bin/kafka-topics.sh --create --topic test --zookeeper localhost:2181 --partitions 1 --replication-f # consume from the topic using the console producer ./bin/kafka-console-consumer.sh --topic test --zookeeper localhost:2181 # produce something into the topic (write something and hit enter) ./bin/kafka-console-producer.sh --topic test --broker-list localhost:9092 Also, I added "flink-connector-kafka" and "kafka-client" dependencies to "pom.xml". But while I run the example of "Monitoring the Wikipedia Edit Stream" I got this error: "cannot resolve symbol FlinkKafkaProducer08". I searched a lot but I could n't find the solution. Would you please help me? Thank you in advance.
