------------------------------------
Hi, I would like to work on this, but preferably after the sampling_rate PR is
merged, because I do not want to clutter the PR queue.
> DecisionTree: eliminate bins for unordered features
> ---------------------------------------------------
>
> Key: SPARK-3381
> URL: https://issues.apache.org/jira/browse/SPARK-3381
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.1.0
> Reporter: Joseph K. Bradley
> Priority: Trivial
>
> Code simplification: DecisionTree currently allocates bins for unordered
> features (in findSplitsBins). However, those bins are not needed; only the
> splits are required. This change will require modifying findSplitsBins, as
> well as modifying a few other functions to use splits instead of bins.
