Using Parlour with custom sql query execution before Sqoop export/import...

....
minor suggestion: instead of returning an empty string in the `getOrElse` with the intention of triggering a `true` response from `StringUtils.isEmpty`, move `getOrElse` to the top level:

```
options.getSqlQuery.fold(false)(!StringUtils.isEmpty(_))
// or alternatively, whatever you find more readable:
options.getSqlQuery.map(!StringUtils.isEmpty(_)).getOrElse(false)
```
