my understanding is that for 2 consumers within the same group, a message goes to only one of the consumers, not both.
but I did a simple test: get the kafka distro, copy the code dir to /tmp/kafka/ then run console consumer from both dirs at the same time bin/kafka-console-consumer.sh --..... all the parameters are the same then I use console producer to dump some messages into the queue. the message does show up on both ends. where am I doing wrong? thanks Yang
