I should mention that I'd actually tested the functionality and done all
the work needed for this piece of functionality to make it into hadoop.
The missing piece is the tomcat shell scripts. If those are packaged
then I just need to do a little work and I can include the functionality
in hadoop. The same work will be needed for other parts of the hadoop
ecosystem.

Looks like tomcat is bundled, which itself is an issue.
I've got a patch that pulls out the d/ling and bundling of tomcat.
That's not a problem.
There's a some stuff in there that's can obviously be paired down.
Here's
the script used to start/stop the service:
http://paste.fedoraproject.org/48852/38253290
This whole script could be replaced by a in-house script just like
/usr/sbin/tomcat, and it should be fairly easy.
A few things I've spotted:
- PRG=$(readlink -f $0) could replace the whole while loop line 19
It's not portable, but we don't care since it'd work on Fedora
- The so-called bug mentioned line 51 is actually documented [1] in
catalina.sh
It works like this by design, I'll notify upstream
I'd prefer to avoid fedora specific changes. We'd like to push as much
as possible upstream and that's difficult enough. Upstream moves fast
and the recent rebase to 2.2.0 was quite a bit of work. If what
upstream provides will work then I'd like to avoid adding more work for
future rebases.
It should be noted that upstream hadoop, and its ecosystem, use
tomcat 6.x
and as part of packaging it we've moved forward to tomcat 7.x.
Unless hadoop's code uses tomcat internals (a valve for instance) this
should not be a problem. I don't have time right now do check that.
Hadoop uses jasper and jspc and we've ported all that stuff forward to
the latest in fedora. There's no need to dive into this mess unless
you're curious or like pain. :)
