Sofia,

I'd recommend using the old (actually, stable) API for development
right now, when using 0.20.2. Do not be confused by the deprecation
marks since it has been un-deprecated for later releases. Using the
stable API should rid you of the trouble of patching the whole thing
up.

I.e., use JobConf+JobClient+'mapred'-package to build and run jobs
instead of the 'Job' class and 'mapreduce' package.
