Unit test failure in ClientUtilsTest - corporate firewall - InetSocketAddress.isUnresolved

[mi...@ubs.com]

Hi everyone, 

I've tried to build kafka-0.11.0.1 and see a unit-test error with the following stack trace:

org.apache.kafka.common.config.ConfigException: No resolvable bootstrap urls given in bootstrap.servers
  at org.apache.kafka.clients.ClientUtils.parseAndValidateAddresses(ClientUtils.java:64)
  at org.apache.kafka.clients.ClientUtilsTest.check(ClientUtilsTest.java:53)
  at org.apache.kafka.clients.ClientUtilsTest.testParseAndValidateAddresses(ClientUtilsTest.java:32)

This appears to result from the offered address remaining unresolved (precis):

  new InetSocketAddress(host, port).isUnresolved()

I'm building this on a corporate intranet with restrictive firewall settings (not that they would obviously impact DNS queries, but it's a possibility).

Regards

Michael
