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 . < Jar
Location and JarName>
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

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
