>                 Key: SPARK-12423
>                 URL: https://issues.apache.org/jira/browse/SPARK-12423
>             Project: Spark
>          Issue Type: Bug
>          Components: Mesos
>    Affects Versions: 1.6.0
>            Reporter: Iulian Dragos
>
> {{spark.mesos.executor.home}} should be an uninterpreted string. It is very possible that this path does not exist on the driver, and if it does, it may be a symlink that should not be resolved. Currently, this leads to failures in client mode.
> For example, setting it to {{/var/spark/spark-1.6.0-bin-hadoop2.6/}} leads to executors failing:
> {code}
> sh: 1: /private/var/spark/spark-1.6.0-bin-hadoop2.6/bin/spark-class: not found
> {code}
> {{getCanonicalPath}} transforms {{/var/spark...}} into {{/private/var..}} because on my system there is a symlink from one to the other.
