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

[Mahesh Abnave]

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 `

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

Hi Mahesh, are you behind any corporate firewall or anything else that prevents you from connecting to IRC?

[Mahesh Abnave]

Hi Fangjin,

No I am not behind any corporate firewall. I am running it on my personal laptop atop VMware.
I dont think my laptop firewall is blocking anything.

How can I know which address it is failing to resolve?
