Github user bowenli86 commented on the issue: https://github.com/apache/flink/pull/4150 ok, I kind of figured out what `promoteTransitiveDependencies` means. I removed explicit dependencies of httpclient and httpcore from `pom.xml`, and made sure http-components are shaded to `org/apache/flink/kinesis/shaded/orsg/apache/http/*` in flink-connector-kinesis_2.11-1.4-SNAPSHOT.jar
