I am triggering an EMR Serverless job using the AWS CLI command. How do I configure the Java version to Java 17?

Question

I am unable to find any easy way of configuring Java 17 with EMR serverless via API or CLI commands. Most of the answers are old. Have there been any updates recently on this?

Hello,

The easiest way would be using "--runtime-configuration" in [Create Application](https://docs.aws.amazon.com/cli/latest/reference/emr-serverless/create-application.html) to pass the spark-default as mentioned in the [link](https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/using-java-runtime.html#using-java-runtime-spark-defaults) to add the below properties for the whole application.

```
{ 
            "classification": "spark-defaults",
            "properties": { 
               "spark.emr-serverless.driverEnv.JAVA_HOME" : "/usr/lib/jvm/java-17-amazon-corretto.x86_64/",
               "spark.executorEnv.JAVA_HOME": "/usr/lib/jvm/java-17-amazon-corretto.x86_64/" 
            }
}
```

Unfortunately, there is no simple option like the UI as the GUI translates the same configuration on client end when the dropdown is selected for different Java version on UI.
