Hi Raymond,
I see that you can make a small correction in your spark-submit command. Your spark-submit command should say: spark-submit --master local --class <full package name>.<className> < Jar Location and JarName> <application arguments> Example: spark-submit --master local \ --class retail_db.GetRevenuePerOrder C:\RXIE\Learning\Scala\spark2practice\target\scala-2.11\spark2practice_2.11-0.1.jar \ C:\RXIE\Learning\Data\data-master\retail_db\order_items \ C:\RXIE\Learning\Data\data-master\retail_db\order_items\revenue_per_order Also, I believe you can "\" to split the commands in the multiple lines even on windows Best Regards, Vamshi T ________________________________ From: Raymond Xie <xie3208...@gmail.com> Sent: Sunday, June 17, 2018 5:07 AM To: user; Hui Xie Subject: spark-submit Error: Cannot load main class from JAR file Hello, I am doing the practice in windows now. I have the jar file generated under: C:\RXIE\Learning\Scala\spark2practice\target\scala-2.11\spark2practice_2.11-0.1.jar The package name is Retail_db and the object is GetRevenuePerOrder. The spark-submit command is: spark-submit retail_db.GetRevenuePerOrder --class "C:\RXIE\Learning\Scala\spark2practice\target\scala-2.11\spark2practice_2.11-0.1.jar" local C:\RXIE\Learning\Data\data-master\retail_db\order_items C:\C:\RXIE\Learning\Data\data-master\retail_db\order_items\revenue_per_order When executing this command, it throws out the error: Error: Cannot load main class from JAR file What is the right submit command should I write here? Thank you very much. By the way, the command is really too long, how can I split it into multiple lines like '\' in Linux? ------------------------------------------------ Sincerely yours, Raymond
