KAFKA-2585; ConsoleConsumer should not hang infinitely upon exception
----
> ConsoleConsumer should not hang infinitely upon exception
> ---------------------------------------------------------
>
> Key: KAFKA-2585
> URL: https://issues.apache.org/jira/browse/KAFKA-2585
> Project: Kafka
> Issue Type: Bug
> Reporter: Dong Lin
> Assignee: Dong Lin
>
> Due to imcompatibility beween Java 1.7 and Java 1.8, if Kafka ConsoleConsumer
> was compiled by Java 1.8 but run by Java 1.7, and if ConsoleConsumer has
> consumer.timeout.ms in the consumer.properties, then when it timesout, it
> will throw the following exception and hang infinitely.
> This will cause problem for e.g. Ducktape system test, which currently runs
> consumer with Java 1.7 and waits for consumer to timeout. This bug causes the
> Ducktape to hang for a long time.
> To prevent ConsoleConsumer to hang in case of such exception, we can wrap
> try/catch around run() and do System.exit(0) at the end of main() in
> ConsoleConsumer.
