--------------------------------------
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.
