--------------------------------
i will do it)
> spark spark.local.dir overwrite for yarn cluster execution
> ----------------------------------------------------------
>
> Key: SPARK-53364
> URL: https://issues.apache.org/jira/browse/SPARK-53364
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 3.5.6, 4.0.0
> Reporter: Antony
> Priority: Major
> Labels: features, hadoop, yarn
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> h3. Context:
> I have a Hadoop cluster with the following configuration:
> One OS disk 200gb
> Two SSD/NVMe disks (1-2 TB each)
> Eight HDDs 16tb
> In Hadoop/YARN, I cannot set different yarn.nodemanager.local-dirs locations
> for the file cache and the application cache.
> h3. Problem:
> i need ssd when start python job for python env filecache.
> i need hdd when start extra big sql job.
> I have seen the spark.local.dir property, but it is for Spark and does not
> solve the YARN-level configuration issue.
> h3. Resolve:
> I want to configure SPARK to use specific directory.
> I want to not always use yarn directories from yarn nodemanager
> here
>
> {code:java}
> def getConfiguredLocalDirs(conf: SparkConf): Array[String] = {
> val shuffleServiceEnabled = conf.get(config.SHUFFLE_SERVICE_ENABLED)
> 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(",")
> } else if (conf.getenv("MESOS_SANDBOX") != null &&
> !shuffleServiceEnabled) {
> // Mesos already creates a directory per Mesos task. Spark should use
> that directory
> // instead so all temporary files are automatically cleaned up when the
> Mesos task ends.
> // Note that we don't want this if the shuffle service is enabled
> because we want to
> // continue to serve shuffle files after the executors that wrote them
> have already exited.
> Array(conf.getenv("MESOS_SANDBOX"))
> } else {
> if (conf.getenv("MESOS_SANDBOX") != null && shuffleServiceEnabled) {
> logInfo("MESOS_SANDBOX available but not using provided Mesos sandbox
> because " +
> s"${config.SHUFFLE_SERVICE_ENABLED.key} is enabled.")
> }
> // In non-Yarn mode (or for the driver in yarn-client mode), we cannot
> trust the user
> // configuration to point to a secure directory. So create a
> subdirectory with restricted
> // permissions under each listed directory.
> conf.get("spark.local.dir",
> System.getProperty("java.io.tmpdir")).split(",")
> }
> } {code}
