Moritz Mack commented on BEAM-14334:
------------------------------------
Looks like BEAM-11653 was failing due do a SparkContext related leak that is
fixed with this issue.
> Avoid using forkEvery in Spark runner tests

> Issue Type: Improvement
> Components: runner-spark, testing
> Reporter: Moritz Mack

> Usage of *{color:#FF0000}forkEvery 1{color}* is typically a strong sign of
> poor quality / bad code and should be avoided:
> * It significantly impacts performance when running tests.
> * And it often hides resource leaks, either in code or worse in the runner
> itself.
