The PySpark code ran without errors with spark submit in yarn client and yarn cluster but couldn't make it work with Oozie workflow. Been trying to get this work for a week now but couldn't figure out exact error. Attached pictures of part of yarn log where I suspect error might be, but not sure. I would appreciate if someone looked over it.

Im new using spark action and oozie workflow with pyspark script. Pasted are the .xml and .properties files here. Please also correct me if my code is having mistakes or needs some work around.

Hi,

 

It looks like the spark job that is started is getting failed.

 

Can you please share the logs for the Spark job. The application ID is mentioned in the snapshot for the spark as it gets initiated but after that it fails.

 

## yarn logs -applicationId <application ID> -appOwner <owner name>

 

Kindly copy the logs in notepad and attach to the case.

 

This will give more leads on this.

 

Regards

Nitish
