             Summary: Executors launched with Spark on K8s client mode should prefix name with spark.app.name
                 Key: SPARK-25148
                 URL: https://issues.apache.org/jira/browse/SPARK-25148
             Project: Spark
          Issue Type: Improvement
          Components: Kubernetes
    Affects Versions: 2.4.0
            Reporter: Timothy Chen


With the latest added client mode with Spark on k8s, executors launched by default are all named "spark-exec-#". Which means when multiple jobs are launched in the same cluster, they often have to retry to find unused pod names. Also it's hard to correlate which executors are launched for which spark app. The work around is to manually use the executor prefix configuration for each job launched.

Ideally the experience should be the same for cluster mode, which each executor is default prefix with the spark.app.name.
