Client connection getting rejected due to SASL authentication

Question

I am facing some issues with authentication in spark application. There are two points. One is the port where I have enabled SASL authentication and one more is the client that has authentication enabled (but not SASL). Whenever the client is trying to connect to this port, the connection request is getting rejected. I have recently started using encryption so I don't know what is wrong.

Answer 1

Seems like you have set the configuration such that the port will accept connections only if SASL encryption is used. To solve this error, you can run the command in the Spark shell:

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --spark.network.sasl.serverAlwaysEncrypt=false
