Actually there was a separate bug for the same issue. Duping...

> 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.
