Oh, sorry, below I meant to say k (the number to reduce to) not p. In both cases p = 1, the first case k = 20, the second case k =100
Also the first error does seem to be running with local hadoop. The error is from looking for a temp file that does exist in the file system, but not in the hadoop tmp based files.
