Error running Hadoop in VirtualBox
Hi,

I have the following configuration - Ubuntu 11.04 as Guest and Host using
VirtualBox and trying to run Hadoop 0.21.0. The host is acting as
namenode/data node/job tracker/task tracker and the guest is acting as a
data node/task tracker.

Every thing works fine in a 'Bridged Adapter' mode, but the problem is that
in this mode I have to be connected to a physical network so that the host
and the guest can talk to each other.

So, I would like to use 'Host-only adapter' so that I can run Hadoop in a
multi-node setup when I am not connected to a physical network. But, I get
the below error in the hadoop-praveensripati-tasktracker-MyMini-Guest.log
file.

Has anyone come across similar problem?
