Timothy Chen created SPARK-25148:
------------------------------------
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.
