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

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

Just to add to @jurban1997 answer.

If you are running windows then make sure that SPARK_HOME and SCALA_HOME environment variables are setup right. SPARK_HOME should be pointing to {SPARK_HOME}\bin\spark-shell.cmd
