Describe the bug

One of our tests changed its behavior after upgrading up to Spark 3.x.

The original comment is located here #3294 (comment)

This issue is to track down the root cause of the behavior change, explain it and fix if necessary.

To Reproduce

$ ./sbt
$ project spark
$ testOnly geotrellis.spark.summary.StatsTileRDDMethodsSpec -- -z "should be able to sample a fraction of an RDD to compute a histogram"
