Soroush Radpour commented on ARROW-8580:
----------------------------------------
The context was using petastorm to read parquet files. I'm mostly concerned
about the exception reporting. Another example can be see here:
[https://github.com/uber/petastorm/issues/547]
pyarrow.lib.ArrowIOError: Arrow error: IOError: b''
It would be great if arrow would print the full stack trace for the underlying
exceptions too (IOError in the second case).
> Pyarrow exceptions are not helpful

> URL: https://issues.apache.org/jira/browse/ARROW-8580
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Reporter: Soroush Radpour
> Priority: Major
>
> I'm trying to understand an exception in the code using pyarrow, and it is
> not very helpful.
> File "pyarrow/_parquet.pyx", line 1036, in pyarrow._parquet.ParquetReader.open
> File "pyarrow/error.pxi", line 99, in pyarrow.lib.check_status
> OSError: IOError: b'Service Unavailable'. Detail: Python exception:
> RuntimeError

> It would be great if each of the three exceptions was unwrapped with full
> stack trace and error messages that came with it.
