I wonder why same role classes are here in elasticsearch repository.

What `org.elasticsearch.xpack.ml.extractor.GeoPointField` is for?  
What `org.elasticsearch.index.mapper.GeoPointFieldMapper` is for?

Any documents?

The mapper class is used when a document with a geo point field is indexed or searched (a little bit simplified, but true at its core), where as the `ml` class is used data feeds in order to extract geo points from the data.

Hope this helps!
