Thanks again Mohammad! Please help me to go further on your advice, since I am not good dealing with hostnames and network conf...
I am using a wired connection to the internet right now and can "ping myself" {ping <myhostname>} and IBI/Hadoop are running fine. But if I change to a wireless connection, I can neither ping myself anymore nor Hadoop. Having said that: What changes in network configuration files (hostname) and in /etc/hosts are necessary in order to ping myself again, this time with a wireless DHCP IP address? Really hope that this is not a dull question... but any help will be much appreciated. Cristián.

To: user@hadoop.apache.org If you don't want to use static IP, use the hostname everywhere in your configuration. But you need to modify the /etc/hosts file everytime to reflect the changes.Regards, Mohammad Tariq On Tue, Aug 14, 2012 at 7:43 PM, Cristian Carranza <cristiancarranz...@hotmail.com> wrote: Julien: Thanks for your prompt response.

You will not only be able to use a static IP, but also keep copies of working systems, make some tests, learn how to setup a cluster with only 1 physical machine. And much more. Julien 2012/8/14 Cristian Carranza <cristiancarranz...@hotmail.com> Hello all in this list! Thank you Harsh J for your help! I decided to post it again in order to properly identify myself in the archive list. My name is Cristián and I am trying to learn Hadoop and to use it in near future... I’ve started to learn Hadoop via Infosphere BigInsights (IBI), Basic Edition, from IBM. But I am facing problems now that make me wonder if there are alternative ways to learn Hadoop. The biggest problem is that IBI demands a static IP address, and this is a tough requirement for me, since I travel a lot for business and always use IP address assigned via DHCP.. Is there a way to use Hadoop without a static IP address? More general question: What are the system requirements for installation of Hadoop? Thank you in advance! Cristián Carranzal.
