------------------------------------

             Summary: 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, Spark Core
    Affects Versions: 3.3.0
            Reporter: pralabhkumar


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
