We are running some tests on upgrading from Kafka 2.10-0.8.2.1 to
2.11-0.10.00. So far, we only upgraded the server. All of the clients
that I could verify are still using the Maven kafka-clients version
0.8.2.1. There are a number of exceptions in the server.log:
[2016-06-07 16:00:00,266] ERROR Closing socket for
172.20.8.19:9092-172.20.3.0:53901 because of error
(kafka.network.Processor)

Any guidance on what the source of this might be?
