------------------------------------
Summary: Make LabeledPointParser public
Key: SPARK-3048
URL: https://issues.apache.org/jira/browse/SPARK-3048
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Xiangrui Meng
Assignee: Xiangrui Meng
`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.
