The error is saying a broker already is running with id=0, or that Zookeeper is corrupt because a broker did not previously cleanly shut down...
In the later case, you can attempt to use zookeeper-shell to rmr /brokers/ids/0, however, this might have more unintended consequences than preforming a restart of Zookeeper as well as the brokers
The only solution which works here is restart the broker and then restart the server.
