> There are conflict in two cases:
> 1. random module is used by pyspark.mllib.feature, if the first part of sys.path is not '', then the hack in pyspark/__init__.py will fail to fix the conflict.
> 2. Run tests in mllib/xxx.py, the '' should be popped out before import anything, or it will fail.
> The first one is not fully fixed for user, it will introduce problems in some cases, such as:
> {code}
> >>> import sys
> >>> import sys.insert(0, PATH_OF_MODULE)
> >>> import pyspark
> >>> # use Word2Vec will fail
> {code}
> I'd like to rename mllib/random.py as random/_random.py, then in mllib/__init.py
> {code}
> import pyspark.mllib._random as random
> {code}
