pralabhkumar updated SPARK-39965:
---------------------------------
Component/s: (was: Spark Core)
> Spark on K8s delete pvc even though it's not being used.
> --------------------------------------------------------
>
> Key: SPARK-39965
> URL: https://issues.apache.org/jira/browse/SPARK-39965
> Project: Spark
> Issue Type: Bug
> Components: Kubernetes
> Affects Versions: 3.3.0
> Reporter: pralabhkumar
> Priority: Minor
>
> In org.apache.spark.util getConfiguredLocalDirs
>
> {code:java}
> if (isRunningInYarnContainer(conf)) {
> // If we are in yarn mode, systems can have different disk layouts so we
> must set it
> // to what Yarn on this system said was available. Note this assumes that
> Yarn has
> // created the directories already, and that they are secured so that only
> the
> // user has access to them.
> randomizeInPlace(getYarnLocalDirs(conf).split(","))
> } else if (conf.getenv("SPARK_EXECUTOR_DIRS") != null) {
> conf.getenv("SPARK_EXECUTOR_DIRS").split(File.pathSeparator)
> } else if (conf.getenv("SPARK_LOCAL_DIRS") != null) {
> conf.getenv("SPARK_LOCAL_DIRS").split(",")
> }{code}
> randomizedInplace is not called conf.getenv("SPARK_LOCAL_DIRS").split(",") .
> This is what used in case of K8s and the shuffle locations are not
> randomized.
> IMHO , this should be randomized , so that all the directories have equal
> changes of pushing the data as was done on yarn side
