How to set client authentication for SSL

Question

I am running a Spark application and have enabled SSL that clients can connect. I want to the clients who are trying to connect to be authenticated before the connection is completed. How can I do this?

Answer 1

By default, this feature is disabled. To enable client authentication, set the authentication property to true. Try this: 

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --spark.ssl.needClientAuth=true
