      I setup RocketMQ (4.1.0-incubating-release) and started it's nameserver and broker as per this instruction on Quick Start. Nameserver and broker started 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).

      It worked for sometime and now it's not working again.
