Robert Metzger commented on FLINK-15557: ---------------------------------------- I don't think we should bump the Kafka dependency version so close to the 1.12.0 release. Testing of the Kafka connector has started already. I will remove the "fix in 1.12" marker. > Cannot connect to Azure Event Hub/Kafka since Jan 5th 2020.
