Spark 1.4 increase maxResultSize memory

You can set spark.driver.maxResultSize parameter in the SparkConf object:

from pyspark import SparkConf, SparkContext

# In Jupyter you have to stop the current context first
sc.stop()

# Create new config
conf = (SparkConf()
    .set("spark.driver.maxResultSize", "2g"))

# Create new context
sc = SparkContext(conf=conf)

You should probably create a new SQLContext as well:

from pyspark.sql import SQLContext
sqlContext = SQLContext(sc)
