I have a problem trying to add jar files to be available on classpath when submitting task to Spark.


In my spark-defaults.conf file I have configuration:

spark.driver.extraClassPath = path/to/folder/with/jars

all jars in the folder are available in SPARK-SHELL


The problem is that jars are not on the classpath for SPARK-MASTER; more precisely – when I submit any job that utilizes any jar from external folder, the java.lang.ClassNotFoundException is thrown.

Moving all external jars into the jars folder solves the situation, but we need to keep external files separatedly.


Thank you for any help

Best regards,
