Rui Li commented on FLINK-20236:
--------------------------------
Let's first figure out which jars are causing the issue. You can go over all
your dependency jars and look for the protobuf classes. Since you got a
conflict, there must be at least two jars containing the same PB class.
> flink-dist.jar and hive-exec.jar have conflict with protobuf-java.jar
