Hi, did you check your user jar if it contains the Kafka classes? Are you building a fat jar? Are you manually excluding any dependencies?
Flink's 0.10.2 Kafka connector depends on Kafka 0.8.2.0 [1] which in turn depends on kafka-clients 0.8.2.0 [2]. And the "kafka-clients" dependency also contains the org.apache.kafka.common.Node class (the LegacyFetcher needs that class).
