crepererum opened a new issue, #4435:
URL: https://github.com/apache/arrow-datafusion/issues/4435
**Is your feature request related to a problem or challenge? Please describe
what you are trying to do.**
It would be nice to get the typed "original" error, even when it is wrapped
into a chain of `ExternalError`, `ArrowError`, `Arc` etc. The original error
could be used to generate HTTP status codes in certain situations, e.g.
"resource exhausted".
**Describe the solution you'd like**
```rust
impl DataFusionError {
/// Get underlying error.
///
/// This may be the same as `self`.
pub fn find_root(&self) -> &Self {...}
}
```
**Describe alternatives you've considered**
String parsing? Sounds like bad code smell.
**Additional context**
See #4434 for improvements on the error generation. See #3940 for an
application.
