Jiefu, Thank you. The three producers can run at the same time. I mean should they be started at exactly the same time? (I have three consoles from each of the three machines and I just start the console command manually one by one) Or a small variation of the starting time won't matter?
Gwen and Jiefu, I have started the three producers at three machines, after a while, all of them gives a java.net.ConnectException: [2015-07-14 12:56:46,352] WARN Error in I/O with producer0-link-0/ 192.168.1.1 (org.apache.kafka.common.network.Selector) java.net.ConnectException: Connection refused......
