[SPARK-17387][PYSPARK] Creating SparkContext() from python without spark-submit ignores user conf ## What changes were proposed in this pull request? The root cause that we would ignore SparkConf when launching JVM is that SparkConf require JVM to be created first. https://github.com/apache/spark/blob/master/python/pyspark/conf.py#L106 In this PR, I would defer the launching of JVM until SparkContext is created so that we can pass SparkConf to JVM correctly. ## How was this patch tested? Use the example code in the description of SPARK-17387, ``` $ SPARK_HOME=$PWD PYTHONPATH=python:python/lib/py4j-0.10.3-src.zip python Python 2.7.12 (default, Jul 1 2016, 15:12:24) [GCC 5.4.0 20160609] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from pyspark import SparkContext >>> from pyspark import SparkConf >>> conf = SparkConf().set("spark.driver.memory", "4g") >>> sc = SparkContext(conf=conf) ``` And verify the spark.driver.memory is correctly picked up. ``` ...op/ -Xmx4g org.apache.spark.deploy.SparkSubmit --conf spark.driver.memory=4g pyspark-shell ``` You can merge this pull request into a Git repository by running: $ git pull https://github.com/zjffdu/spark SPARK-17387 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/14959.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #14959 ---- commit f97776152c1e1d02bf5049eb182e37a7e4d5ed52 Author: Jeff Zhang <zjf...@apache.org> Date: 2016-09-05T08:37:06Z [SPARK-17387][PYSPARK] Creating SparkContext() from python without spark-submit ignores user conf commit 8ade76d1c81dea2c57bc70191e1c5da8ebf6b64e Author: Jeff Zhang <zjf...@apache.org> Date: 2016-09-05T11:17:38Z fix code style commit f24f9167e4225ea6f8c6b0868c4831934a2f0f34 Author: Jeff Zhang <zjf...@apache.org> Date: 2016-09-05T12:30:40Z fix unit test commit b07c5749235bd17bb434710170f55f3c752cf7dc Author: Jeff Zhang <zjf...@apache.org> Date: 2016-09-20T06:12:04Z address comment ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
