----------------------------------
Summary: 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
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.
