---------------------------------------
i just ran into an issue because of this when trying to upgrade to spark 2.1.0
breeze 0.12 introduces a dependency on shapeless 2.0.0, which is old (april
2014) and not compatible with the version(s) we are using
> Upgrade breeze version to 0.12

> Key: SPARK-16494
> URL: https://issues.apache.org/jira/browse/SPARK-16494
> Project: Spark
> Issue Type: Improvement
> Components: ML, MLlib
> Reporter: Yanbo Liang
> Assignee: Yanbo Liang
> Priority: Minor
> Fix For: 2.1.0
>
>
> breeze 0.12 has been released for more than half a year, and it brings lots
> of new features, performance improvement and bug fixes.
> One of the biggest features is LBFGS-B which is an implementation of LBFGS
> with box constraints and much faster for some special case.
> We would like to implement Huber loss function for {{LinearRegression}}
> (SPARK-3181) and it requires LBFGS-B as the optimization solver. So we should
> bump up the dependent breeze version to 0.12.
> For more features, improvements and bug fixes of breeze 0.12, you can refer
> the following link:
