Jiaxin Shan created SPARK-30626:
-----------------------------------

             Summary: [K8S] Spark driver pod doesn't have SPARK_APPLICATION_ID
                 Key: SPARK-30626
                 URL: https://issues.apache.org/jira/browse/SPARK-30626
             Project: Spark
          Issue Type: Improvement
          Components: Kubernetes
    Affects Versions: 2.4.4, 3.0.0
            Reporter: Jiaxin Shan


This should be a minor improvement.

The use case is we want to look up environment variables and create application folder and redirect driver logs to application folder.  Executors has it and we want to make a change to driver as well.

We need SPARK_APPLICATION_ID inside the pod to organize logs
