* | | | | Do not inherit master's PYTHONPATH on workers. | Josh Rosen | 2013-07-29 | 1 | -3/+2 |
|/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes SPARK-832, an issue where PySpark would not work when the master and workers used different SPARK_HOME paths. This change may potentially break code that relied on the master's PYTHONPATH being used on workers. To have custom PYTHONPATH additions used on the workers, users should set a custom PYTHONPATH in spark-env.sh rather than setting it in the shell. | ||||

* | | | SPARK-815. Python parallelize() should split lists before batching | Matei Zaharia | 2013-07-29 | 1 | -2/+9 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | One unfortunate consequence of this fix is that we materialize any collections that are given to us as generators, but this seems necessary to get reasonable behavior on small collections. We could add a batchSize parameter later to bypass auto-computation of batch size if this becomes a problem (e.g. if users really want to parallelize big generators nicely) | ||||

* | Do not launch JavaGateways on workers (SPARK-674). | Josh Rosen | 2013-02-01 | 4 | -18/+25 |
| | | | | | | | | | | | 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. | ||||
