-------------------------------------

             Summary: deprecate weights and use coefficients instead in ML models
                 Key: SPARK-10592
                 URL: https://issues.apache.org/jira/browse/SPARK-10592
             Project: Spark
          Issue Type: Improvement
          Components: ML, PySpark
    Affects Versions: 1.6.0
            Reporter: Xiangrui Meng
            Priority: Critical


The name `weights` becomes confusing as we are supporting weighted instanced. As discussed in https://github.com/apache/spark/pull/7884, we want to deprecate `weights` and use `coefficients` instead:

* Deprecate but do not remove `weights`.
* Only make changes under `spark.ml`.
