Best setup for multiple nutch users on one server

[Bryan Woliner <br...@gmail.com>]

For a while I have been the only one testing nutch on my server, but now I
have a couple of colleagues that are going to start working on my nutch
project. For those of you who also have several people working with nutch on
the same server, I have a couple of questions:

1. Do you have one installation of NUTCH for each user or do you all work
from the same installation?

I can't really think of a reason why multiple nutch installations would be
neccessary, since I can currently call nutch commands while other nutch
processes are already running.

2. Do you have one installation of TOMCAT for each user or do you all work
from the same installation?

It seems to me like you would need multiple tomcat installations if multiple
users want to be able to start and stop tomcat without interfering with
other user's work.

Thanks,
Bryan

Hi Bryan,
running multiple nutch on one box is possible but difficult.
The problem is that tomcat and also nutch (0.8 map reduce/ ndfs) use  
a set of tcp port ports, that are already blocked in case a other  
unix user already runs nutch.

The best way to go, is that you first use a subversion or cvs as  
centralized repository for your customized code, than all developers  
can share code and working together on the same  code basis.
Beside that each developer should run a tiny test instance of nutch  
on her developer machine.
In the end it is a good idea - to have a script that download once a  
day the code from cvs and run a test suite and deploy the code on  
your 'big' server.
http://cruisecontrol.sourceforge.net/ is a helpful tool.
