Classpath issues when running spark-submit

[User16869510359]

How to identify the jars used to load a particular class. I am sure I packed the classes correctly in my application jar. However, looks like the class is loaded from a different jar. I want to understand the details so that I can ensure to use the right version of the jar and avoid conflict.

Adding the below configurations at the cluster level can help to print more logs to identify the jars from which the class is loaded.

• spark.executor.extraJavaOptions=-verbose:class
• spark.driver.extraJavaOptions=-verbose:class
