Change encryption key length fro Spark application

Question

Hey. My Spark application is using a 128-bit encryption key. I want to increase this length. How can I do this?

Answer 1

You can do this by running the following command in Spark shell:

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --spark.network.crypto.keyLength = 192

The valid length is 128, 192 and 256
