Stevo Slavic updated MAHOUT-1341:
---------------------------------
Description:
When running {{examples/bin/classify-20newsgroups.sh}} and choosing clean
option, working directory gets initialized first (so 20newsgroups dataset gets
downloaded if not already in the working directory) just to have working
directory deleted. So cleaning already clean working directory will take
unnecessarily long.
For clean task we should skip working directory initialization and just clean
things up.
