Gwen Shapira commented on KAFKA-1618:
-------------------------------------
I can't think of other client server system that doesn't guess default ports.
Our users use ZooKeeper (at least), so they must be used to clients that guess
the default port.
However, I agree that this is not critical and mostly a "nice to have".
What's important is that the behavior has to be consistent everywhere.
If users have to wonder "why does this URI works in X but not in Y", we are
doing something wrong. If we decide that guessing is wrong, none of our tools
should accept just a server name.

> When running console producer with just "localhost" as the broker list, I get
> ArrayIndexOutOfBounds exception.
> I expect either a clearer error about arguments or for the producer to
