* [MINOR] [MLLIB] rename some functions of PythonMLLibAPIYanbo Liang2015-06-253-5/+5
| | | | | | | | | | | | | | | | | | | | | | | Keep the same naming conventions for PythonMLLibAPI. Only the following three functions is different from others ```scala trainNaiveBayes trainGaussianMixture trainWord2Vec ``` So change them to ```scala trainNaiveBayesModel trainGaussianMixtureModel trainWord2VecModel ``` It does not affect any users and public APIs, only to make better understand for developer and code hacker.

* [SPARK-7899] [PYSPARK] Fix Python 3 pyspark/sql/types module conflictMichael Nazario2015-05-292-8/+0
| | | | | | | | | | | | | | | This PR makes the types module in `pyspark/sql/types` work with pylint static analysis by removing the dynamic naming of the `pyspark/sql/_types` module to `pyspark/sql/types`. Tests are now loaded using `$PYSPARK_DRIVER_PYTHON -m module` rather than `$PYSPARK_DRIVER_PYTHON module.py`. The old method adds the location of `module.py` to `sys.path`, so this change prevents accidental use of relative paths in Python.
