----------------------------
Resolution: Fixed
> Separate driver spark home from executor spark home
> ---------------------------------------------------
>
> Key: SPARK-2454
> URL: https://issues.apache.org/jira/browse/SPARK-2454
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.0.1
> Reporter: Andrew Or
> Assignee: Andrew Or
> Fix For: 1.1.0
>
>
> The driver may not always share the same directory structure as the
> executors. It makes little sense to always re-use the driver's spark home on
> the executors.
> https://github.com/apache/spark/pull/1244/ is an open effort to fix this.
> However, this still requires us to set SPARK_HOME on all the executor nodes.
> Really we should separate this out into something like `spark.executor.home`
> and `spark.driver.home` rather than re-using SPARK_HOME everywhere.
