I setup RocketMQ (4.1.0-incubating-release) on macOS Sierra (10.12.3) and started it's nameserver and broker as per this instruction. Nameserver and broker start up well. However I can't create a new topic or see topic list or see a status of any topic. I get the following error.
$ sh bin/mqadmin updateTopic -n localhost:9876 -c DefaultCluster -r 2 -w 2 -t MY_TOPIC

I tried both compiling the source myself and downloaded the compiled binary from Apache's site. I also tried 4.0.0-incubating-release binary. It allowed to me to list the topics using sh mqadmin topicList. But it didn't allow me to create a new topic owing to the above exception.
I don't see any relevant log in any of the rocketmq logs (namesrv.log, broker.log or remoting.log).
I wonder if it's a bug or some problem with my setup.
Adding the following two lines to the configuration file (broker.conf) solved the issue.
