I am getting myself acquainted with Esri's GIS Tools for Hadoop. Working with Hive.
One of my tables, A, has user lat-lons. Another, B, has landmarks and their lat-lons. How do I join two tables so that I get all landmarks names and their locations from B within a given distance (radius) from each location in A? How to replicate a k-NN query, if possible?
Can I do it with Esri's GIS Tools for Hadoop?
I have heard of Hadoop GIS and SpatialHadoop, but there are limitations - cannot get them working.
