Hi Guys,\nI am running Superset in Docker on macOS locally.\nI'd like to connect to Apache Impala and MySQL on another host (development cluster).\n\nI have followed the instructions that were suggested here: <https://preset.io/blog/2020-05-18-install-db-drivers/>\nand installed `impyla` as well as `mysqlclient`. Also, I then rebuilt the Docker image, so it would recognize the changes.\nHowever, this did not bring any resolve.\n\nI keep getting error messages saying that SQLAlchemy does not know the dialect I am trying to use, even though it should have been installed...\n\nThis is style of URI I am using for Impala: `impala://{host}:21050/default`\nand for MySQL: `mysql://{user}:{pass}@{host}:3306/default`\n\nAny help would be much appreciated.
