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.
