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 b47d054cfc Remove use of abc.ABCMeta due to cloudpickle issue. 
cloudpickle runs into issues while pickling subclasses of AccumulatorParam,
which may be related to this Python issue:

    http://bugs.python.org/issue7689

This seems hard to fix and the ABCMeta wasn't necessary, so I removed it.
