I am ingesting data from a shapefile (the TM_WORLD_BORDERS-0.3.shp) into geomesa (on accumulo) via the native api. I then want to, again using the Native Api, query the data for anything in geomesa that contains a point (lat,lon), given by the user (basically any polygon in geomesa that contains the point).
More-or-less mimicking the "Q. What did I click on?: Use a point for to Check Polygon Layers" from http://docs.geotools.org/latest/userguide/library/main/filter.html
GeoMesaQuery q = GeoMesaQuery.GeoMesaQueryBuilder.builder()
.within(-180.0,-90.0,180.0,90.0) // needed or the query throws a null-pointer ex
.filter(ff.contains(ff.property("the_geom"), ff.literal(point)))
.build();
however, when I run the query I get an error (in accumulo):

I can see that my feature has a *geom type, but NOT a "the_geom" type. I then tried to overwrite the SimpleFeatureView 'populate' and 'getExtraAttributes' methods, but getExtraAttributes won't let me bind a geometry... (note: I also tried to give the setAttribute the gmtr from the populate signature with the same error).
GeoMesaIndex<Shapefile> index = AccumuloGeoMesaIndex.build(
config.getString("tableName"),
config.getString("zookeeperHostPort"),
config.getString("accumuloInstance"),
config.getString("user"),
config.getString("password"),
false,
new ShapefileValueSerializer(),
new SimpleFeatureView<Shapefile>() {
@Override
public void populate(SimpleFeature sf, Shapefile t, String string, byte[] bytes, Geometry gmtr, Date date) {
sf.setAttribute("the_geom", t.the_geom);
}
@Override
public List<AttributeDescriptor> getExtraAttributes() {
AttributeTypeBuilder atb = new AttributeTypeBuilder();
return Lists.newArrayList(
atb.binding(Geometry.class).buildDescriptor("the_geom")
);
}
});
with error:

So with all that said, is it possible to do a polygon point containment check using a filter using GeoMesa's Native Api? I have not been able to query the geometry using ff.property(any version of "geom", e.g., "the_geom", "*geom", etc)
