How can I pass environment variable to project which run on EMR Serverless?

In my PySpark project I'm using a python package that uses Dynaconf so I need to set the following environment variable - ENV_FOR_DYNACONF = platform. The problem is I don't understand how can I pass this environment variable to the EMR Serverless job run.

I've tried this -

os.environ['ENV_FOR_DYNACONF'] = platform

At the beginning of the code, but it didn't work and in any case, I want to understand what is the right way to pass env variables to the EMR.

Can anyone help?

Solution

To pass environment variables in EMR Serverless, you can use the following spark job properties in sparkSubmitParameters :

spark.executorEnv.[KEY] to pass env variables to the executors.
spark.emr-serverless.driverEnv.[KEY] to pass env variables to the driver.

Example :

"sparkSubmitParameters": "--conf spark.emr-serverless.driverEnv.ENV_FOR_DYNACONF=platform"
