Suhas Vasu commented on FALCON-1228:
------------------------------------
Ideally any directory can exist in /tmp/ of the user, we shouldn't be banking
on the availability of the file named {{log}} in /tmp/
I suggest we use a file named {{/tmp/falcon-log}}. The chances of name
conflicts will be drastically reduced.

> this particular test wants to write to a file at {{/tmp/log}}, as a result of
> which it threw this exception.
