There was a problem hiding this comment.
It would be good to restrict this to calls on Spark DataFrame/DataSet objects.
Looking at https://sourcegraph.com/search?q=context:global+lang:scala+unionall&patternType=standard&sm=1 we see that a lot of other libraries also use a unionAll function that we would not want to rewrite.

Same with add a negative test (e.g. call unionAll on a non-DataFrame and make sure we don't transform it). |
… test example use unionAll in slick
