Agreed. Given that netstat showed that the webserver was bound to the 
public interface (not, it's probably an EC2 issue.

Assuming that's the same exception you had the previous logs, the master 
just hadn't started yet and the tracer tried to perform an RPC to it. 
The last line of the tracer log implies that it successfully talked to 
the master and registered itself in ZooKeeper. You should ignore this 
exception in this case.

If you're seeing it repeatedly, that's a different issue (send more logs)
