Ismael Juma commented on KAFKA-2405:
------------------------------------
We have 43 instances of `System.exit` in `core` and a few instances of
`Runtime.halt`. Is there a document explaining when it's OK to exit and when it
is not?
> KafkaHealthCheck kills the JVM in handleSessionEstablishmentError
> -----------------------------------------------------------------
>
> Key: KAFKA-2405
> URL: https://issues.apache.org/jira/browse/KAFKA-2405
> Project: Kafka
> Issue Type: Bug
> Components: core
> Reporter: jaikiran pai
> Assignee: jaikiran pai
> Fix For: 0.8.3
>
>
> The current code in KafkaHealthCheck in trunk does this:
> {code}
> override def handleSessionEstablishmentError(error: Throwable): Unit = {
> fatal("Could not establish session with zookeeper", error)
> System.exit(-1)
> }
> {code}
> thus terminating the JVM. A session establishment error shouldn't cause the
> JVM to terminate.
