I have code files (.hql) in s3 which was running on Hive. But now, I need to run them on the Databricks cluster. 
I can rename the files to .sql and add comment "-- Databricks notebook source" on top of the files to treat them as single cell notebook. But I am not getting way to run that file directly on Databricks.

Also, I don't see any way to bring multiple files from s3 to Databricks workspace as running notebook is supported only in two ways - Workspace or Git.
