Hi,
I am checking out how your repo is structured and have some questions. I haven't used java before so I would really appreciate it if you can clarify some points for me.
As an example for route interpolation the following query is executed:
insert overwrite table {provider_prefix}_cdr_by_uid_trip_routing_array_apd partition (pdt) select uid,f_routing(uid,arr,"{osm}","{voronoi}"), pdt from {provider_prefix}_cdr_by_uid_trip_realloc_array_apd where (size(arr)>0 and size(arr)<={max_size_interpolation})
which uses f_routing
and that function is in turn defined in initial_hive_commands_interpolation.json
as:
"create temporary function f_routing as 'jp.ac.ut.csis.pflow.turkcell.hive.udf.TurkcellRoutingUDF'"
Am I supposed to have these Hive user defined functions somewhere? I downloaded PFlow from sekilab github, but can't find any such related functions.
Similarly some functions like FindPolygon are defined as "create temporary function FindPolygon as 'com.apichon.mobility.hive.udf.FindPolygon'"
, which are UDFs written by Dr. Apichon Witayangkurn I assume.
Thanks a lot in advance.
