> Evaluator: support isLargerBetter on connect ML
> -----------------------------------------------
>
> Key: SPARK-50884
> URL: https://issues.apache.org/jira/browse/SPARK-50884
> Project: Spark
> Issue Type: Sub-task
> Components: Connect, ML, PySpark
> Affects Versions: 4.0.0, 4.1.0
> Reporter: Bobby Wang
> Assignee: Bobby Wang
> Priority: Major
> Labels: pull-request-available
>
> Currently, on connect ML, users couldn't access isLargerBetter from
> Evaluator, since isLargerBetter is using py4j way to access the corresponding
> method on scala side. But for current ml connect design, we don't support
> that.
> To fix this issue, there could be two solutions,
> # rewrite isLargerBetter in pyspark client side to follow the same
> implementation as the scala side.
> # resolve it with a new proto.
