This PR sets
spark.kubernetes.executor.useDriverPodIPtotrueby default viasetIfMissinginSparkAppSubmissionWorker#buildDriverConf, next to the otheroperator-injected defaults. Since it uses
setIfMissing, an explicit value in theapplication spec is always respected.
Why are the changes needed?
spark.kubernetes.executor.useDriverPodIP(added in Spark 4.1.0 via SPARK-53944) makesexecutor pods connect to the driver using the driver pod IP instead of the driver
Servicehostname, bypassing Kubernetes DNS. The operator fully manages the driver podlifecycle, and in cluster mode the driver is not restarted (the application terminates if
it dies), so the pod IP is stable for the application's lifetime. Enabling it by default
avoids DNS propagation delays/failures on executor startup and reduces CoreDNS load. It is
a no-op for Spark versions older than 4.1.0.
spark.kubernetes.executor.useDriverPodIPspark#52650Does this PR introduce any user-facing change?
Yes. When
spark.kubernetes.executor.useDriverPodIPis unset, the operator now defaultsit to
true(previously Spark's default offalse). Applications that set it explicitlyare unaffected.
How was this patch tested?
