RE: Hello! - Hadoop: System Requirements.

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.

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

your purpose is learn / dev / demo, it would be a good idea to use a VM.

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.

  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

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
