>                 URL: https://issues.apache.org/jira/browse/SPARK-24446
>             Project: Spark
>          Issue Type: Bug
>          Components: YARN
>    Affects Versions: 2.3.0
>            Reporter: Marcelo Vanzin

>            Priority: Minor

> When YARN runs the application's main command, it does it like this:
> {code}
> bash -c "<your command goes here>"
> {code}
> The way Spark injects the library path into that command makes it look like this:
> {code}
> bash -c "LD_LIBRARY_PATH="/foo:/bar:/baz:$LD_LIBRARY_PATH" <rest of the command>"
> {code}
> So that works kinda out of luck, because the concatenation of the strings creates a proper final command... except if you have something like a space or an ampersand in the library path, in which case all containers will fail with a cryptic message like the following:
> {noformat}
> WARN cluster.YarnSchedulerBackend$YarnSchedulerEndpoint: Executor for container container_1475411358336_0010_01_000002 exited because of a YARN event (e.g., pre-emption) and not because of an error in the running job.
> {noformat}
> And no useful log output.
