* [SPARK-4897] [PySpark] Python 3 supportDavies Liu2015-04-161-1/+8

Known issue: unpickle array from Pyrolite is broken in Python 3, those tests are skipped. TODO: ec2/spark-ec2.py is not fully tested with python3.

It looks like: ![api doc](https://cloud.githubusercontent.com/assets/40902/4538272/9e2d4f10-4dec-11e4-8d96-6e45a8fe51f9.png) Author: Davies Liu <davies.liu@gmail.com> Closes #2689 from davies/docs and squashes the following commits: bf4a0a5 [Davies Liu] fix links 3fb1572 [Davies Liu] fix _static in jekyll 65a287e [Davies Liu] fix scripts and logo 8524042 [Davies Liu] Merge branch 'master' of github.com:apache/spark into docs d5b874a [Davies Liu] Merge branch 'master' of github.com:apache/spark into docs 4bc1c3c [Davies Liu] refactor 746d0b6 [Davies Liu] @param -> :param 240b393 [Davies Liu] replace epydoc with sphinx doc
* [SPARK-3309] [PySpark] Put all public API in __all__Davies Liu2014-09-031-0/+2
| | | | | | | | | | | | | | Put all public API in __all__, also put them all in pyspark.__init__.py, then we can got all the documents for public API by `pydoc pyspark`. It also can be used by other programs (such as Sphinx or Epydoc) to generate only documents for public APIs. Author: Davies Liu <davies.liu@gmail.com> Closes #2205 from davies/public and squashes the following commits: c6c5567 [Davies Liu] fix message f7b35be [Davies Liu] put SchemeRDD, Row in pyspark.sql module 7e3016a [Davies Liu] add __all__ in mllib 6281b48 [Davies Liu] fix doc for SchemaRDD 6caab21 [Davies Liu] add public interfaces into pyspark.__init__.py
* [SPARK-2627] [PySpark] have the build enforce PEP 8 automaticallyNicholas Chammas2014-08-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in [SPARK-2627](https://issues.apache.org/jira/browse/SPARK-2627), we'd like Python code to automatically be checked for PEP 8 compliance by Jenkins. This pull request aims to do that. Notes: * We may need to install [`pep8`](https://pypi.python.org/pypi/pep8) on the build server. * I'm expecting tests to fail now that PEP 8 compliance is being checked as part of the build. I'm fine with cleaning up any remaining PEP 8 violations as part of this pull request. * I did not understand why the RAT and scalastyle reports are saved to text files. I did the same for the PEP 8 check, but only so that the console output style can match those for the RAT and scalastyle checks. The PEP 8 report is removed right after the check is complete. * Updates to the ["Contributing to Spark"](https://cwiki.apache.org/confluence/display/SPARK/Contributing+to+Spark) guide will be submitted elsewhere, as I don't believe that text is part of the Spark repo.

* Fix some other Python tests due to initializing JVM in a different wayMatei Zaharia2013-12-291-2/+3
| | | | | | | | The test in context.py created two different instances of the SparkContext class by copying "globals", so that some tests can have a global "sc" object and others can try initializing their own contexts. This led to two JVM gateways being created since SparkConf also looked at pyspark.context.SparkContext to get the JVM.
