RPMs won't work on Ubuntu, but we're almost finished with DEBs, which will
work on Ubuntu.  Shoot Todd an email if you want to try out our DEBs:

<todd@cloudera.com>

Are you asking about choosing a Linux distribution?  The problem with Ubuntu
is that it changes very frequently and generally uses relatively new
software, making it a great desktop distribution, but perhaps not as good of
a stable server distribution.  (Note that the LTS Ubuntu releases are
supported longer but still user newer, possibly unstable software.)  I think
that the majority of Linux server people use Redhat derivatives, in
particular RHEL and CentOS, as they're not updated frequently and use stable
software (RHEL costs money; CentOS is free).  That said, CentOS is annoying
to administer if you're hoping to use a version of Python newer than 2.4.
I'm sure that the Debian people on this list will yell at me for saying
Redhat derivatives are the majority, but we'll see I guess.

So anyway, give Todd a shout if you want to try DEBs out.  Otherwise, if
you're interested in going down the Redhat derivative route (Fedora, RHEL,
CentOS), you can use the RPMs.
