Joseph K. Bradley updated SPARK-13944:
--------------------------------------
    Description: 
Separate out linear algebra as a standalone module without Spark dependency to 
simplify production deployment. We can call the new module mllib-local, which 
might contain local models in the future.

The major issue is to remove dependencies on user-defined types.

The package name will be changed from mllib to ml. For example, Vector will be 
changed from `org.apache.spark.mllib.linalg.Vector` to 
`org.apache.spark.ml.linalg.Vector`. The return vector type in the new ML 
pipeline will be the one in ML package; however, the existing mllib code will 
not be touched. As a result, this will potentially break the API. Also, when 
the vector is loaded from mllib vector by Spark SQL, the vector will 
automatically converted into the one in ml package.
