How to change default Spark dashboard port

Question

I am not able to access Spark dashboard because I have another service running on port 4040,4041,4042. So, I want to change the port for Spark dashboard. How can I do this?

Answer 1

You can change it dynamically while using the spark submit command. The syntax is as follows:

val sc = new SparkContext(new SparkConf())

./bin/spark-submit <all your existing options> --spark.ui.port=<new port>
