Invalid topics prevent broker start-up
--------------------------------------
Key: KAFKA-104
URL: https://issues.apache.org/jira/browse/KAFKA-104
Project: Kafka
Issue Type: Bug
Reporter: Joel Koshy
Priority: Minor
Excerpt from a trace we saw today. If there is a topic directory with an
invalid name, then the registerMBean call throws an exception which eventually
results in a start failure. Also, if you try sending messages with an invalid
topic to a broker, the broker's logs get flooded with these exceptions. Easy
fix is to wrap the registerMBean with Utils.swallow; and probably prevent
ProducerRequest from accepting invalid topics.
