Hello 

Thank you very much, but I imported "FlinkKafkaProducer09" and changed "FlinkKafkaProducer08" to it. Then problem solved.

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.

 

Cheers,

Kostas

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.
