Facing out-of-memory errors in Spark driver

Question

HI. I am new to Spark and I am running a driver job. I am getting out-of-memory errors. It is working for smaller data(I have tried 400MB) but not for larger data (I have tried 1GB, 2GB). Please help

Answer 1

I am guessing that the configuration set for memory usage for the driver process is less and the memory required is high. By default, it is set to 1g. Try increasing it. 

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --conf spark.driver.memory=4g
