Xiangrui Meng updated SPARK-3048:
---------------------------------
Description: `LabeledPointParser` is used in `MLUtils.loadLabeledPoint`.
Making it public may be useful to parse labeled points from other data sources,
e.g., DStream. Now we have a util function called
`MLUtils.loadStreamingLabeledPoints`, which increases the complexity of the
API. I really want to make `parse` as a method of `LabeledPoint$` instead of
creating a new class `LabeledPointParser`, but it is hard to extend a case
class with a static method in a binary compatible way. (was:
