Liang-Chi Hsieh resolved SPARK-23265. ------------------------------------- Fix Version/s: 3.0.0 Resolution: Fixed Issue resolved by pull request 20442 [https://github.com/apache/spark/pull/20442] > Update multi-column error handling logic in QuantileDiscretizer > --------------------------------------------------------------- > > Key: SPARK-23265 > URL: https://issues.apache.org/jira/browse/SPARK-23265 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 2.3.0 > Reporter: Nick Pentreath > Assignee: Huaxin Gao > Priority: Major > Fix For: 3.0.0 > > > 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. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
