-----------------------------------
Summary: [FlightRPC][Python] Regression in DoPut error handling
Key: ARROW-16592
URL: https://issues.apache.org/jira/browse/ARROW-16592
Project: Apache Arrow
Issue Type: Bug
Reporter: Lubo Slivka
In PyArrow 8.0.0, any error raised while handling DoPut on the server results
in FlightInternalError on the client.
In PyArrow 7.0.0, errors raised while handling DoPut are propagated/converted
to non-internal errors.
---
Example: on 7.0.0, raising FlightCancelledError while handling DoPut on the
server would propagate that error including extra_info all the way to the
FlightClient. This is not the case anymore on 8.0.0.
The FlightInternalError contains extra detail that is derived from the
cancelled error though:
{code:java}
/arrow/cpp/src/arrow/flight/client.cc:363: Close() failed: IOError: <error
message from FlightError is here>. Detail: Cancelled. gRPC client debug
