描述

We have LightGBM - Quantile Regression for Drug Discovery.ipynb as PySpark code example.

I would like to request Spark Scala example as API does not exactly the same (can copy paste) between PySpark and Spark.

An Spark example will be helpful for beginner.

研究方向
Review the existing PySpark notebook at 'notebooks/samples/LightGBM Quantile Regression for Drug Discovery.ipynb' to understand the workflow. Then refer to the SynapseML LightGBM Scala API documentation to implement a standalone Scala app that replicates the same functionality. Check if the repository has other Scala examples for guidance.
