Hi Kafka Users, I am a first timer for kafka. After installing kafka2.3.1, Scala2.11, Java OpenJDK11.0.4 in a Ubuntu Docker image, I could not add any topic to the kafka. After fixing the following problem, it works now:
In /opt/kafka_2.11-2.3.1/config/server.properties, there is a line like this: group.initial.rebalance.delay.ms=0advertised.host.name=kafka It obviously should be divided into two lines like this: group.initial.rebalance.delay.ms=0 advertised.host.name=kafka If anybody knows the reason, please let us know. Thank you, Garry
