[jira] [Comment Edited] (KAFKA-5118) Improve message for Kafka
failed startup with non-Kafka data in data.dirs
[ https://issues.apache.org/jira/browse/KAFKA-5118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15982092#comment-15982092 ]

------------------------------------------------------
I remember 0.10.2.0 checks whether the directory name contains the dash before substring-ing it. There is another possibility that your non-Kafka directory ends with `-delete`. Right?

> Key: KAFKA-5118
> URL: https://issues.apache.org/jira/browse/KAFKA-5118
> Project: Kafka
> Issue Type: Improvement
> Components: core
> Affects Versions: 0.10.2.0
> Reporter: Dustin Cote
> Priority: Minor
>
> 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.
