Hi Thomas,

I have been thinking about an official Hadoop Debian package for a while

The main issue that prevents the inclusion of the current Cloudera
package into Debian is that it depends on Sun's Java. I think it would
be interesting, at least for an official Debian package, to depend on
OpenJDK in order to make it possible to distribute it in "main" instead
of "contrib".

Also, note that in order to fit into Debian's package autobuilding
system, some scripts will probably require some tweaking. For instance,
by default Hadoop downloads dependencies at build time using ivy, but
Debian packages should use already existing packages. Incidentally,
Hadoop depends on some libraries that aren't available in Debian yet,
such as xmlenc, so there is even more work to do.

(Anyway, I'm interested in the package, so let me know if you need some
help and want to set up a group on alioth or something.)
