I am stuck with the same thing. Tables were inferred without any problem, but when I query it with Athena it shows empty result

It is because that the location of those tables is not the folder path, it points specific file under the same folder.
Athena does not support reading from such kind of tables although Glue ETL can read them.

If you want Athena to read those tables, you can move each file to separate folder and run Glue crawler for each path, or you can just read from Glue ETL and write into separate locations and populate table definition from the job.
