Review Comment:
For most people who have just used RocketMQ, they just want to successfully
run the PushConsumer, but they will get a "connect to null failed" message. In
addition, namesrvAddr is also hard coded in PullConsumer, so I think hard
coding namesrvAddr is helpful for novices who have just learned RocketMQ.
