We generally recommend sticking with whatever Linux is already common inside
your organization. Hadoop itself should run equally well on CentOS 5, RHEL
5, or any reasonably recent Ubuntu/Debian. It will probably be OK on any
other variety of Linux as well (eg SLES), though they are less commonly
used.
The reason that RHEL/CentOS is most common for Hadoop is simply that it's
most common for large production Linux deployments in general, and
organizations are hesitant to add a new flavor for no benefit.
Personally I prefer running on reasonably recent Ubuntu/Debian since you get
some new kernel features like per-process IO accounting (for iotop), etc.
I am busy debugging why my laptop doesn't boot since upgrading to ubuntu
9.10 at the weekend, they've done some off things to filesystem to
produce faster boots that I'm not convinced work
