Issues getting Dumbo to work

[Robert]

I'm just starting to use Dumbo, and I haven't been able to get the
example code to run yet. In the example directory, I run the following
command:

python ./wordcount.py map < ./brian.txt | sort | \ python wordcount.py
red > wc_output.txt

I get the following output:

Traceback (most recent call last):
File "./wordcount.py", line 13, in <module>
dumbo.run(mapper,reducer,reducer)
File "build/bdist.linux-x86_64/egg/dumbo/core.py", line 240, in run
File "/usr/lib/python2.6/UserDict.py", line 22, in __getitem__
raise KeyError(key)
KeyError: 'dumbo_mrbase_class'
Command 'python' is available in '/usr/bin/python'
python: command not found

I'm attempting to run this on Ubuntu 10.04. I've tried running it with
both Python 2.6 and Python 2.7, and I've tried installing Dumbo via
ez_install and from source. I get the same error regardless of the
version of Python being used or the method of Dumbo install. A couple
of google searches and perusing the issues tracker yielded no
information. Any suggestions?

Thanks!

I just tested this on Mac OS X 10.6 with Python 2.6 with Dumbo
installed via easy install, and the issue persists.

Thanks!

I solved the issue. I was getting my information about how to run
dumbo programs from an old blog post (and the first Google search
result for dumbo hadoop) instead of the wiki.

Thanks,
Robert
