Josh Rosen e211f405bc Use spark.local.dir for PySpark temp files (SPARK-580). 2013-02-01 11:50:27 -08:00
Josh Rosen 9cc6ff9c4e Do not launch JavaGateways on workers (SPARK-674). 
The problem was that the gateway was being initialized whenever the
pyspark.context module was loaded.  The fix uses lazy initialization
that occurs only when SparkContext instances are actually constructed.

I also made the gateway and jvm variables private.

This change results in ~3-4x performance improvement when running the
PySpark unit tests.

Josh Rosen 9f211dd3f0 Fix PythonPartitioner equality; see SPARK-654. 
PythonPartitioner did not take the Python-side partitioning function
into account when checking for equality, which might cause problems
in the future.
