Da,
Do you have permissions to run iostat? That could help you to find
persistent IO activity from other processes.
Another possibility is that your system has a RAID controller without a
cache memory card, from my experience that makes writes awfully slow.

Hi,
Seems that you need to add your hostname/IP pair in /etc/hosts in both
nodes. Also it looks that you need to setup your configuration files
correctly.
This guides can be helpful for you:

Hello Jon,
Could you please verify that your node can resolve the host name?
It would be helpful too if you can attach your configuration files and the
output of:
HADOOP_ROOT_LOGGER=DEBUG,console hadoop fs -ls /
as Todd suggested.
Cheers,

Hello Cavus,
is your Job Tracker running on localhost? It would be great if you can
provide more information about your current Hadoop setup.

a look into their website.
