Description

In my scene, I get a model file in lightgbm format which can be loaded into a booster, and then I need to deploy the model in distributed environment to predict some score. As lightgbm doesn't support transforming booster into lgbmclassifier(https://github.com/microsoft/LightGBM/issues/1942), is it possible to support native booster interface in Mars?

Research direction

The issue provides no file or test entry point. Start by locating Mars's LightGBM support and the path that loads a model for distributed prediction, then compare the requested native Booster input with the linked LightGBM limitation; done means a Booster model file can be loaded and used for distributed scoring.
