These files are the configuration of Hive version 2.7.3 on edgenode. the file hive-jdbc-2.3.7-standalone.jar could not be upload due to the size. This mean you need to dowload from https://downloads.apache.org/hive/hive-3.1.2/ and paste into the file jdbc. File jdbc/hive-jdbc-2.3.7-standalone.jar is 57.00 MB
Now, Hive was configured using Postgres 9.5 as a DB. This mean that that drivers, jdbc and scheme are for postgres.
