Hi Dhanuka,
>From the exceptions, it seems you have changed the Kafka version to
'universal'. You can solve your problem in any of the following ways:
- Change Kafka version to 0.11. You only have a jar of 0.11 version in your
lib folder.
- Add flink-connector-kafka_2.11-1.7.0.jar to your lib folder if you want
to use 'universal'.
Best, Hequn
