Jun Rao commented on KAFKA-101:
-------------------------------
Taylor, this would suggest a synchronization issue during append to the log.
Looking at the code, the append is always synchronized on the lock of the
segment file. Could you reproduce the problem on 0.7?

> Currently, if a consumer consumes a topic and the topic doesn't exist, the
> topic is created automatically. Sometimes this can be confusing. Often, an ad
> hoc user may put a wrong topic name in the consumer and thus create many
> unnecessary topics.
