Weichen Xu commented on SPARK-22331: ------------------------------------ OK, it seems not breaking current code in spark, but it is possible to influence user extension code. e.g., some user create his own `evaluator` class and in `metricName` param he use `ParamValidators.inArray(Array("aa", "AA"))` as allowedParams. > Make MLlib string params case-insensitive > ----------------------------------------- > > Key: SPARK-22331 > URL: https://issues.apache.org/jira/browse/SPARK-22331 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 2.2.0 > Reporter: yuhao yang > Priority: Minor > > Some String params in ML are still case-sensitive, as they are checked by > ParamValidators.inArray. > For consistency in user experience, there should be some general guideline in > whether String params in Spark MLlib are case-insensitive or not. > I'm leaning towards making all String params case-insensitive where possible. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
