[SPARK-2652] [PySpark] Turning some default configs for PySpark
Add several default configs for PySpark, related to serialization in JVM.
spark.serializer = org.apache.spark.serializer.KryoSerializer
spark.kryo.referenceTracking = False
spark.serializer.objectStreamReset = 1
This will help to reduce the memory usage during RDD.partitionBy()
