Hello, Previously, we were using Kafka version 0.10.0.0 and Kafka Connect 0.10.0.0. Everything was working fine, but we would like to upgrade Connect to the latest version 0.10.1.1 to make use of some new features. We do not want to upgrade Kafka if we don't have to. However, it seems that the new Connect is unable to connect to Kafka whereas the old one connects just fine. I see this message repeated in the logs until some timeout is reached.
