Hello, This approach unfortunately doesn’t work for job submission for me. It works in the shell, but not when submitted. I ensured the (only worker) node has desired directory.
Neither specifying all jars as you suggested, neither using /path/to/jarfiles/* works. Could you verify, that using this settings you are able to submit jobs with according dependencies, please?

For example spark.driver.extraClassPath /home/hduser/jars/ojdbc6.jar:/home/hduser/jars/jconn4.jar spark.executor.extraClassPath /home/hduser/jars/ojdbc6.jar:/home/hduser/jars/jconn4.jar this will work as long as all nodes have that directory. The other alternative is to mount the shared directory as NFS mount across all the nodes and all the noses can read from that shared directory HTH Dr Mich Talebzadeh LinkedIn https://www.linkedin.com/profile/view?id=AAEAAAAWh2gBxianrbJd6zP6AcPCCdOABUrV8Pw http://talebzadehmich.wordpress.com Disclaimer: Use it at your own risk.

I am aware of the parameters used when submitting the tasks (--jars is working for us). But, isn’t there any way how to specify a location (directory) for jars „in global“ - in the spark-defaults.conf??

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, Jan
