Review Comment:
I have the same error class defined here:
https://github.com/apache/spark/pull/41989/files#diff-2823e146fc0e6bddff3505b5bee6e2b855782d9f71e900e6f9099fc97d1fffa6R280.
I will change the error class name in my PR.

Review Comment:
Why do we make `analyze` a `staticmethod`?
For example, we could have a UDTF defined in this way:
```
class MyUDTF:
def __init__(self):
self.some_boolean_value = ...
def analyze(self, a, b):
if self.some_boolean_value:
return StructType(..)
...
```
