Re: can't consume from partitions due to KAFKA-3963

You could have had split brain where multiple brokers thought they were the controller. This has been a problematic piece of Kafka for a long time and only in the last release or two have some of the edge cases been cleaned up. To force a controller re-election, remove the "/controller" znode

Re: can't consume from partitions due to KAFKA-3963

As far as I have debugged my issues, server.log files were of the most use, they have errors and 'caused by' reasons. Probably, the leader broker was down and the followers were not able to replicate data now. 1. What are your min isr and replication settings? 2. Is your producer working? 3. What

RE: can't consume from partitions due to KAFKA-3963

Thanks for the tips. As far as a broker being down, the situation is confused because a broker was definitely down, but I think we brought it down when we were trying to address the problem a few days ago. I can't say for sure that it wasn't down before, but we do have a monitor to catch that

Re: Kafka streams failed for internal topics with FailOnInvalidTimestamp even with WallclockTimestampExtracto
