> SPARK-22397 added support for multiple columns to {{QuantileDiscretizer}}. If both single-
and mulit-column params are set (specifically {{inputCol}} / {{inputCols}}) an error is thrown.
> However, SPARK-22799 added more comprehensive error logic for {{Bucketizer}}. The logic
for {{QuantileDiscretizer}} should be updated to match. *Note* that for this transformer,
it is acceptable to set the single-column param for {{numBuckets }}when transforming multiple
columns, since that is then applied to all columns.
