Could you please let me know the difference between org.apache.kafka.connect.converters.ByteArrayConverter‌ and io.confluent.connect.replicator.util.ByteArrayConverte‌​r? Does both these classes serve the same purpose?

@pradeepcheers There is no functional difference. We added a version to Kafka itself so it would be available across all connectors -- we saw a number of connectors including their own, so it made sense to include it out of the box since it's really simple anyway and should have no real maintenance cost.
