Wes McKinney created ARROW-6884:
-----------------------------------
Summary: [Python][Flight] Make server-side RPC exceptions more
friendly?
Key: ARROW-6884
URL: https://issues.apache.org/jira/browse/ARROW-6884
Project: Apache Arrow
Issue Type: Improvement
Components: FlightRPC, Python
Reporter: Wes McKinney
Fix For: 1.0.0
Here is what an error looks like when a client RPC fails in the server
{code}
E pyarrow.lib.ArrowException: Unknown error: gRPC returned unknown error,
with message: a bytes-like object is required, not 'str'
E In ../src/arrow/python/flight.cc, line 201, code: CheckPyError(). Detail:
Python exception: TypeError
{code}
The "line 201, code:" business is added by -DARROW_EXTRA_ERROR_CONTEXT=ON so
the normal use won't see this
It might be nice to re-raise the same exception type in the client with some
extra context added to make clear that it is a server-side error
