I have the same issue running inside the Docker Container. Does anyone have
a solution to this?
This is query string I add into "SQLAlchemy URI"
druid://broker_druid:8082/druid/v2/sql/
This is the error I get:
ERROR: {"error": "Connection failed!\n\nThe error message returned
was:\nCan't load plugin: sqlalchemy.dialects:druid"}
If I login to the Superset Container and check for the PyDruid version, I am
running the latest version (pydruid==0.5.9)
From within the shell of the Superset container I can use curl successfully
to query the broker and get results back (using SQL).
However, if I open up a Python repl in the Superset Container, and I use:
```
from sqlalchemy import *
from sqlalchemy.engine import create_engine
from sqlalchemy.schema import *
engine = create_engine('druid://localhost:8082/druid/v2/sql/')
```
I get the same error I get from the Superset UI mentioned above.
engine = create_engine('druid://broker_druid:8082/druid/v2/sql/')
