### 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 #31238 Closes #32650 from HyukjinKwon/SPARK-32194. Authored-by: Hyukjin Kwon <gurwls223@apache.org> Signed-off-by: Hyukjin Kwon <gurwls223@apache.org> |
