Why does spark-submit and spark-shell fail with “Failed to find Spark assembly JAR. You need to build Spark before running this program.”?

Question

I was trying to run spark-submit and I get \"Failed to find Spark assembly JAR. You need to build Spark before running this program.\" When I try to run spark-shell

Answer 1

If your spark binaries are in a folder where the name of the folder has spaces (for example, "Program Files (x86)"), it didn't work. I changed it to "Program_Files", then the spark_shell command works in cmd.
