Jason Rosenberg commented on KAFKA-2222:
----------------------------------------
Agreed. I think in the past there was a clear code path where any IOException
occurring during a file access would cause an immediate shutdown. I'm not sure
if that path still exists?
> Write "Input/output error" did not result in broker shutdown

> Key: KAFKA-2222
> URL: https://issues.apache.org/jira/browse/KAFKA-2222
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 0.8.1.2
> Reporter: Jason Rosenberg
>
> We had a disk start failing intermittently, and began seeing errors like this
> in the broker. Usually, IOExceptions during a file write result in the
> broker shutting down immediately. This is with version 0.8.2.1.
