> Today, if you try to startup a broker with some non-Kafka data in the data.dirs you end
up with a cryptic message:
> {code}
> [2017-04-21 13:35:08,122] ERROR There was an error in one of the threads during logs
loading: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 (kafka.log.LogManager)

> [2017-04-21 13:35:08,124] FATAL [Kafka Server 3], Fatal error during KafkaServer startup.
Prepare to shutdown (kafka.server.KafkaServer) 
> java.lang.StringIndexOutOfBoundsException: String index out of range: -1 
> {code}
> It'd be better if we could tell the user to look for non-Kafka data in the data.dirs
and print out the offending directory that caused the problem in the first place.
