--------------------------------------
Summary: UnknownHostError looking for a ZK node crashes the broker
Key: KAFKA-620
URL: https://issues.apache.org/jira/browse/KAFKA-620
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.7.1
Environment: linux. Amazon's AMI
Reporter: Matthew Rathbone
If you totally kill a zookeeper node so that it's hostname no longer resolves
to anything, the broker will die with a java.net.UnknownHostException.
You will then be unable to restart the broker until the unknown host(s) is
removed from the server.properties.
We ran into this issue while testing our resilience to widespread AWS outages,
if you can point me to the right place, I could have a go at fixing it?
Unfortunately, I suspect the issue might be in the non-standard Zookeeper
library that kafka uses.
