- Is Ubuntu a good O.S. for running Hadoop?  I’ve tried to learn in the
past using Red Hat & Infosphere Biginsights, but I need a free O.S.
If you want a free O.S , ubuntu is good but if you are familiar with RedHat
then you may want to have look at Scientific Linux (Its free as well)

- Is there a way to learn Hadoop without a static IP address? That was
really a problem for me when dealing with Infosphere, since I travel
frequently.
If you got a laptop with you then thats all you need to learn hadoop.
Hadoop can be installed in a pseudo distributed mode on a single machine
and you can use it with localhost all the time.

for the basics, all you need is a java IDE .  Hadoop Map/Reduce can run in
local filesystem mode without any kind of HDFS backing.

Does your user have permissions to read/write on the dfs directories you
made?

try changing the directory ownerships to the user which is running hadoop.

Yes user owns the directory and had right permissions, still i don't
understand what could be the issue.
ls -ltr ~/hadoop-1.0.4/logs/history
total 0
drwxr-xr-x+ 1 garamini mkgroup 0 Jan  2 22:15

If you like RedHat, consider Centos also; it is a nearly-complete clone of the RHEL distro.

- Is Ubuntu a good O.S. for running Hadoop?  I've tried to learn in the past using Red Hat & Infosphere Biginsights, but I need a free O.S.
If you want a free O.S , ubuntu is good but if you are familiar with RedHat then you may want to have look at Scientific Linux (Its free as well)

what about other directories like hdfs directories and tmp directories ?

Hi john,which would be a better option between Linux and windows from learning perspective of Hadoop?

If you like RedHat, consider Centos also; it is a nearly-complete clone of the RHEL distro.

If you want a free O.S , ubuntu is good but if you are familiar with RedHat then you may want to have look at Scientific Linux (Its free as well)

I personally find Windows easier to use, however it is not a supported Hadoop production environment, and I *think* you have to use Cygwin under Windows even for development.
Given that, if you want to use a Windows machine and performance is not a consideration, you could spin up a VirtualBox VM under Windows and install CentOS on it.

Uhm...

Well, you can talk to Microsoft and Hortonworks about Microsoft as a platform.

Depending on the power of your laptop, you could create a VM and run hadoop in a pseudo distributed mode there.

You could also get an Amazon Web Services account and build a small cluster via EMR...

In terms of OS, Centos is free and its a solid platform for Hadoop.
You could then download Cloudera's CHDx and run it in a pseudo distributed cluster on a single node.
Lots of options...

I would say Linux, because in your job you're most likely going to use a
*nix-type system instead of Windows for hosting Hadoop, so it's good to
gain experience with whatever headaches come along.  Further, you're
also learning Linux simultaneously, killing two birds with one stone.
