> Prior to SPARK-4834, configuring spark.local.dir in the driver would affect the local directories created on the executor.  After this patch, executors will always ignore this setting in favor of directories read from {{SPARK_LOCAL_DIRS}}, which is set by the standalone worker based on the worker's own configuration and not the application configuration.
> This change impacts users who configured {{spark.local.dir}} only in their driver and not via their cluster's {{spark-defaults.conf}} or {{spark-env.sh}} files.  This is an atypical use-case, since the available local directories / disks are a property of the cluster and not the application, which probably explains why this issue has not been reported previously.
> The correct fix might be comment + documentation improvements.
