Sean Owen resolved SPARK-16618.
-------------------------------
    Resolution: Not A Problem

Use MulticlassMetrics, but, with 4 points, ROC or PR curves are going to be 
mostly meaningless.

> Binary classification using Naive bayes

> spark naive bayes does not support for binary classification . I checked with 
> both ML and MLLIB . According to current scenario Naive bayes only support 
> multi class classification . We have to write code for binary classification 
> also .As we know logistic regression support binary classification .   Mean 
> we can not get ROC and PR curve using spark naive , even if we give only two 
> class( category or distinct label values)
