There was a problem hiding this comment.
Maybe call this parse instead of apply, should be friendlier

@mengxr Since I can't find the comment where you mentioned me (probably deleted), I believe you don't need my review on this. :-) |

This is a patch to address @mateiz 's comment in apache#245 MLUtils#loadLibSVMData uses an anonymous function for the label parser. Java users won't like it. So I make a trait for LabelParser and provide two implementations: binary and multiclass. Author: Xiangrui Meng <[email protected]> Closes apache#345 from mengxr/label-parser and squashes the following commits: ac44409 [Xiangrui Meng] use singleton objects for label parsers 3b1a7c6 [Xiangrui Meng] add tests for label parsers c2e571c [Xiangrui Meng] rename LabelParser.apply to LabelParser.parse use extends for singleton 11c94e0 [Xiangrui Meng] add return types 7f8eb36 [Xiangrui Meng] change labelParser from annoymous function to trait
* Add manageiq-providers-openstack job for public clouds
