Project: Spark
Issue Type: Improvement
Components: ML
Affects Versions: 1.4.0
Reporter: Xiangrui Meng
In 1.4.0, we introduced ML attribute API to embed feature/label attribute info
inside DataFrame's schema. However, the API is not very friendly to use. In
1.5, we should re-visit this API and see how we can improve it.
