spark-submit Error: No main class set in JAR; please specify one with --class

Question

I am trying to execute a spark application using spark-submit.

c:\temp>spark-submit --master yarn  ./SparkExamples.jar --class com.examples.WordCount
Error: No main class set in JAR; please specify one with --class
Run with --help for usage help or --verbose for debug output

The main class file is existing in the jar file. I also checked there is a MANIFEST.MF file which holds the main class name.

Manifest-Version: 1.0

Main-Class: com.examples.WordCount

what am I missing?

Answer 1

Try providing --class parameter first before ./SparkExamples.jar

spark-submit --master yarn  --class com.examples.WordCount ./SparkExamples.jar
