Hi Scott,<br>
<br>
The MapReduce was first implemented for Hadoop 0.20.0 and was
updated MapReduce module to work with Hadoop 0.21. From svn log, the
last version working with hadoop 0.20.0 should be 26264. So if you
update your mapreduce module to this version, it should work with
0.20.203.<br>
<br>
Please keep in mind that this module is not well tested and
hasn't been publicly released. If you find any bugs, please let us
know. Thanks.<br>

and I've noticed that it uses Hadoop 0.21. We are targeting an
operational environment where we would like to be using Hadoop
0.20.203 instead of Hadoop 0.21. Is there some particular
functionality in Hadoop 0.21 that is needed or can I safely make
changes to use 0.20.203 with the map-reduce module? I appreciate
any advice that you have.<br>
