             Summary: Setting spark.local.dir in driver no longer overrides the standalone worker's local directory setting
                 Key: SPARK-7108
                 URL: https://issues.apache.org/jira/browse/SPARK-7108
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.3.0, 1.2.1
            Reporter: Josh Rosen
            Priority: Critical


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.
