Nicolas Liochon commented on SPARK-3431:
----------------------------------------
Yep, it seems ok from a maven point of view. The safest at the beginning it to
try forkCount=1/reuseForks=false, then you can increase the forkCount. The
default is forkCount=1/reuseForks=true, but I doubt it's the issue as Sean
already reproduced it outside of maven.

> Running all the tests in {{dev/run-tests}} takes up to 2 hours. A common
> strategy to cut test time down is to parallelize the execution of the tests.
> Doing that may in turn require some prerequisite changes to be made to how
> certain tests run.
