> If you use {{spark-submit}} in {{cluster}} mode to submit a job to a Spark Standalone cluster, and the {{JAVA_HOME}} environment variable is set on the submitting machine, then DriverRunner will attempt to use the _submitter's_ JAVA_HOME to launch the driver process (instead of the worker's JAVA_HOME), which can cause the job to fail unless the submitter and worker have Java installed in the same location.
> This has a pretty simple fix: read JAVA_HOME from {{sys.env}} instead of {{command.environment}}; PR pending shortly.
