[jira] [Created] (SPARK-23265) Update multi-column error handling logic in QuantileDiscretizer

Nick Pentreath created SPARK-23265:
--------------------------------------

             Summary: Update multi-column error handling logic in QuantileDiscretizer
                 Key: SPARK-23265
                 URL: https://issues.apache.org/jira/browse/SPARK-23265
             Project: Spark
          Issue Type: Documentation
          Components: ML
    Affects Versions: 2.3.0
            Reporter: Nick Pentreath


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.
