I'll remove Surefire from the dependency list. When you say "also refer to it
under <build>" where else exactly do I need to add references?
> Parallelize execution of tests

> Key: SPARK-3431
> URL: https://issues.apache.org/jira/browse/SPARK-3431
> Project: Spark
> Issue Type: Improvement
> Components: Build
> Reporter: Nicholas Chammas
> Assignee: Nicholas Chammas
>
> 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.
