Review comment:
A few observations:
- This code is run at least when `superset load examples` is executed, even
when not connected to a druid cluster, causing an `exit(1)` every time. I think
this needs to be refactored so that this code is only called when needed, e.g.
in the specific code blocks where they are needed.
- The error message should probably be wrapped in a `_('message')` to make
it translatable. Furthermore, if the message is wrapped in triple quotes, the
leading spaces on the next rows will be included in the message. I believe
linters will prefer single quotes over many rows. So something like this:
```python
try:
...
except Import Error:
print(_('pydruid and requests are optional dependencies, and '
'it seems they are not installed on your system. Aborting...'))
))
```
