Carlo Mazzaferro updated ARROW-10460:
-------------------------------------
Description:
Authentication with FlightClient changed from version 1.0.1 to 2.0.0 and is
undocumented.
{{>>> from pyarrow import __version__}}{{>>>
print(__version__}}{{'1.0.1'}}{{>>> from handlers import
ApiKeyClientAuthHandler # custom handler}}
{{ >>> from pyarrow.flight import (}}
{{ ... FlightClient)}}
{{ >>> client = FlightClient(location="grpc+tcp://xxxxxxxxxx.com")}}
{{ >>> client.authenticate(ApiKeyClientAuthHandler(api_key="xxxxx"))}}
And the exact same code in 2.0.0 breaks
>>> from pyarrow import __version__
>>> print(__version__)
'2.0.0'
>>> from handlers import ApiKeyClientAuthHandler # custom handler
>>> from pyarrow.flight import (
... FlightClient)
>>> client = FlightClient(location="grpc+tcp://xxxxxxxxxx.com")
>>> client.authenticate(ApiKeyClientAuthHandler(api_key="xxxxx"))
{{Traceback (most recent call last):}}
{{ File "scratch.py", line 15, in <module>}}
{{
client.authenticate(ApiKeyClientAuthHandler(api_key="c8669431-8172-4c24-8b17-300330e10f1b"))}}
{{ File "pyarrow/_flight.pyx", line 1149, in
pyarrow._flight.FlightClient.authenticate}}
{{ File "pyarrow/_flight.pyx", line 70, in
pyarrow._flight.check_flight_status}}
{{pyarrow._flight.FlightUnavailableError: gRPC returned unavailable error, with
message: failed to connect to all addresses}}
