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.
 Cristián.

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

Thanks!

if
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
  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
