Renan DelValle commented on AURORA-1723:
----------------------------------------

This actually came up last year when I was working bringing custom executors to 
Aurora. If recall correctly, the concern then was that since the executor runs 
as root in most clusters, there is a risk that an arbitrary file downloaded 
externally can cause some serious damage. Following this school of thought, 
I've currently made any URI downloaded into the sandbox non-executable, but if 
we decide that we should leave this up to the user I'm fine with that as well.

Maybe [~wfarner] can provide a better explanation and weigh in on this as well.

> Adding support for Aurora Tasks to be capable of using the [Mesos 
> Fetcher|http://mesos.apache.org/documentation/latest/fetcher/] by allowing 
> the client to provide arbitrary URIs at which resources can be retrieved. 
> Resources will be marked non-executable to avoid security risks.
