EMR serverless spark properties file



How do we pass application.conf or properties file to spark jobs on emr serverless, in standard EMR we copy properties or conf files to master node /home/hadoop/?

1 Answer

You can place the file(s) in S3 and refer them using the standard --files parameter in spark parameters. The distinction in Serverless being if you intend to load this properties files and need to create an InputStream you will need to use SparkFiles.get(fileName) instead of just filename in the traditional EC2 based EMR cluster, read more about this here
