Major Description
I incorrectly setup the configuration file to have the metrics go to /var/kafka/metrics while the logs were in /var/kafka. On startup I received the following error then the daemon exited:
30 [main] INFO kafka.log.LogManager - [Log Manager on Broker 0] Loading log 'metrics'
32 [main] FATAL kafka.server.KafkaServerStartable - Fatal error during KafkaServerStable startup. Prepare to shutdown

This was on a brand new cluster so no data or metrics logs existed yet.
Moving the metrics to their own directory (not a child of the logs) allowed the daemon to start.
Took a few minutes to figure out what was wrong.
