Working towards it!  But we need to review some docs for 1.6 first.

Kai Sasaki commented on SPARK-11520:


[~josephkb] The metrics of {{RegressionMetrics}} seems to be based on 
{{MultivariateStatisticalSummary}}. And current {{RegressionMetrics}} does not 
support weighted samples as argument. So we can pass the weighted samples to 
MultivariateStatisticalSummary ({{MultivariateOnlineSummarizer}}) and calculate 
metrics for regression metrics. 
Is this assumption correct? Can I work on this JIRA, if possible?
