I upgraded the kafka from 0.10.0 to 2.5 and also logstash from 2.4 to 7.5.1 after upgrade logstash is sending empty messages to Kafka( i can see this in kafka UI) but I can see messages in kafka UI which is forwarded from logstash 2.4 (this is another host running with logstash 2.4)
issue:
Logstash is unable to forward messages to kafka topics. in the logstash log I'm seeing kafka client version 2.3 which is a jar version. What is the supported kafka version with logstash 7.5 kafka documentation is not updated with this information?
