Spark2.1.0 incompatible Jackson versions 2.7.6

Answer 1

FYI. For my case, I'm using spark and kafka-streams in the app, while kafka-streams uses com.fasterxml.jackson.core 2.8.5. Adding exclude as below fixed the issue

(gradle)

compile (group: "org.apache.kafka", name: "kafka-streams", version: "0.11.0.0"){
    exclude group:"com.fasterxml.jackson.core"
}
