Subject Re: Flink 0.10.2 and Kafka 0.8.1
Date Mon, 18 Apr 2016 15:38:19 GMT
Turns out when I remove the explicit dependency on kafka_2.10 v. 0.8.1,
then the dependencies are properly included. Guess there was a conflict
somehow? I'll need to figure out if the rest of the code is fine with
kafka_2.10 v. 0.8.2.0 as well.
