* [SPARK-8032] [PYSPARK] Make version checking for NumPy in MLlib more robustMechCoder2015-06-021-1/+3
| | | | | | | | | | | | | | | | The current checking does version `1.x' is less than `1.4' this will fail if x has greater than 1 digit, since x > 4, however `1.x` < `1.4` It fails in my system since I have version `1.10` :P Author: MechCoder <manojkumarsivaraj334@gmail.com> Closes #6579 from MechCoder/np_ver and squashes the following commits: 15430f8 [MechCoder] fix syntax error 893fb7e [MechCoder] remove equal to e35f0d4 [MechCoder] minor e89376c [MechCoder] Better checking 22703dd [MechCoder] [SPARK-8032] Make version checking for NumPy in MLlib more robust
* [SPARK-7899] [PYSPARK] Fix Python 3 pyspark/sql/types module conflictMichael Nazario2015-05-291-8/+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. Author: Michael Nazario <mnazario@palantir.com> Closes #6439 from mnazario/feature/SPARK-7899 and squashes the following commits: 366ef30 [Michael Nazario] Remove hack on random.py bb8b04d [Michael Nazario] Make doctests consistent with other tests 6ee4f75 [Michael Nazario] Change test scripts to use "-m" 673528f [Michael Nazario] Move _types back to types

* SPARK-1421. Make MLlib work on Python 2.6Matei Zaharia2014-04-051-5/+1
| | | | | | | | | | | The reason it wasn't working was passing a bytearray to stream.write(), which is not supported in Python 2.6 but is in 2.7. (This array came from NumPy when we converted data to send it over to Java). Now we just convert those bytearrays to strings of bytes, which preserves nonprintable characters as well.
