java.nio.channels.UnresolvedAddressException when running druid sample app

Question

I am trying out druid.io with zookeeper 34.6 on fedora 20 x64. U am following tut [here]( http://druid.io/docs/latest/Tutorial:-A-First-Look-at-Druid.html)

After huge effort I am able to run zookeeper. Now when I run the server of sample druid app It gives me below error. Notice that it says Inventory initialized

2015-06-21T17:14:03,472 INFO [ServerInventoryView-0] io.druid.client.BatchServerInventoryView - Inventory Initialized

So which address it is failing to resolve? I am new to both druid and zookeeper so must be missing some architectural understanding.

This problem can occur with the wikipedia firehose if you are behind a corporate firewall. If you try at home, do you see the same problem? FWIW, you will get a faster response by posting questions here: https://groups.google.com/forum/#!forum/druid-user
