>
> org.apache.spark.ml.util.TempDirectory should remove the temp directories it
> creates, but it does not (at least not locally on my machine).
> This is an issue for the several new tests for ML model import/export, which
> leave a bunch of empty temp directories.
> At first inspection, I don't see why this problem is occurring. It must mean
> that {{org.apache.spark.util.Utils.deleteRecursively}} is successful except
> for its {{finally}} section. That section is tested in UtilsSuite unit
> tests, so it should be working.
