Resolution: Won't Fix
> Remove handleInvalid from QuantileDiscretizer
> ---------------------------------------------
>
> Key: SPARK-18587
> URL: https://issues.apache.org/jira/browse/SPARK-18587
> Project: Spark
> Issue Type: Improvement
> Components: ML
> Reporter: Yanbo Liang
> Assignee: Yanbo Liang
> Priority: Critical
>
> HandleInvalid only happens when {{Bucketizer}} transforming a dataset which
> contains NaN, however, when the training dataset containing NaN,
> {{QuantileDiscretizer}} will always ignore them. So we should keep
> {{handleInvalid}} in {{Bucketizer}} and remove it from
> {{QuantileDiscretizer}}.
