### What changes were proposed in this pull request?
This PR proposes to use a proper built-in exceptions instead of the plain `Exception` in Python.
While I am here, I fixed another minor issue at `DataFrams.schema` together:
```diff
- except AttributeError as e:
- raise Exception(
- "Unable to parse datatype from schema. %s" % e)
+ except Exception as e:
+ raise ValueError(
+ "Unable to parse datatype from schema. %s" % e) from e
```
Now it catches all exceptions during schema parsing, chains the exception with `ValueError`. Previously it only caught `AttributeError` that does not catch all cases.
### Why are the changes needed?
For users to expect the proper exceptions.
### Does this PR introduce _any_ user-facing change?
Yeah, the exception classes became different but should be compatible because previous exception was plain `Exception` which other exceptions inherit.
### How was this patch tested?
Existing unittests should cover,
Closes#31238Closes#32650 from HyukjinKwon/SPARK-32194.
