Failed to start master for Spark in Windows

Question

Same problem as Failed to start master for spark in windows 10 which is also not solved.

My spark is working well by testing pyspark.cmd and spark-shell.cmd

Answer 1

After executing spark-class org.apache.spark.deploy.master.Master, just goto http://localhost:8080 to get ip:port. And then open another command shell to execute spark-class org.apache.spark.deploy.worker.Worker spark://IP:PORT
