Joseph K. Bradley closed SPARK-5027.
------------------------------------
    Resolution: Won't Fix

I'm closing this issue.  I'd like us to add LBFGS support for SVMs, but it will need to be done in the DataFrame-based API.  I've linked the new JIRA issue.

>          Components: MLlib
>    Affects Versions: 1.2.0

>   Our team has done the comparison test for ann. The test results are in   “https://github.com/apache/spark/pull/1290”
>   And we find the performance of svm using LBFGS is higher than svm using SGD, so I want to add SVMWithLBFGS interface to mllib.
