EMR on EKS local files

Hello,

Can you please confirm, if this (my.jar --cfg /local/path/config.cfg) is a spark config? If yes, then you can pass this spark config through spark-submit.

• The spark-submit script in Spark’s bin directory is used to launch applications on a cluster. [1]

Also, please feel free to check out our AWS Integration and Automation Github page on EMR on EKS here -

https://github.com/aws-ia/terraform-aws-eks-blueprints/tree/main/examples/analytics/emr-on-eks

Furthermore, information regarding sparkSubmit and example in terms of AWS CLI command for EMR Serverless has been mentioned on our AWS docs here -

https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/jobs-spark.html

conf = An arbitrary Spark configuration property.

Configuration that you provide as part of sparkSubmitParameters using --conf.

Additionally, in regards to containers, you can pass config files to a container using configmaps as a ConfigMap is an API object used to store non-confidential data in key-value pairs. Pods can consume ConfigMaps as environment variables, command-line arguments, or as configuration files in a volume. [2]

• A ConfigMap allows you to decouple environment-specific configuration from your container images, so that your applications are easily portable.

• Caution: ConfigMap does not provide secrecy or encryption.
