Java heap space OutOfMemoryError in pyspark spark-submit (spark version:2.2)

Anu B Nair

Hi,

I have a data set size of 10GB(example Test.txt).

I wrote my pyspark script like below(Test.py):

from pyspark import SparkConf
from pyspark.sql import SparkSession
from pyspark.sql import SQLContext
spark = SparkSession.builder.appName("FilterProduct").getOrCreate()
sc = spark.sparkContext
sqlContext = SQLContext(sc)
lines = spark.read.text("C:/Users/test/Desktop/Test.txt").rdd
lines.collect()

Then I am executing the above script using below command :

spark-submit Test.py --executor-memory  15G --driver-memory 15G

Then I am getting error like below:

17/12/29 13:27:18 INFO FileScanRDD: Reading File path: file:///C:/Users/test/Desktop/Test.txt, range: 402653184-536870912, partition values: [empty row]

Please let me know how to resolve this ?
