How to increase Garbage Collection speed?

Please help me with Garbage Collection problem. I have created a Spark application which leaves out a lot of garbage. I know I have to optimize it but for now, I need a quick fix. Please tell me how to fasten the garbage collection interval.

The time interval between Garbage Collection is set to 30min by default. If you want the Garbage Collection to happen sooner, then reduce the time. Try this:

val sc = new SparkContext(new SparkConf())
./bin/spark-submit <all your existing options> --spark.cleaner.periodicGC.interval=20
