Solución alternativa

1. Edit Amazon S3 or other source types to remove location type, and set location type to 'None'.
2. Add Calculate Field tool and connect with the big data analytic source.
3. Create a new calculation of Geometry, specify an expression of: "Point({"x":$feature.longitude,"y":$feature.latitude,"spatialReference":{"wkid":4326}})". Change as needed for other field names.
