URL: https://github.com/apache/arrow/issues/37140
### Describe the usage question you have. Please include as many useful
details as possible.
I use MacOS Big Sur. I use venv with Python 3.8, PyArrow and Pandas were
installed by pip only. I did not use setup.py in arrow.
Some issue with standard arrow/python/examples/flight/client.py.
server.py works fine.
I started the server.py
(venv) user@users-MBP python %
/Users/user/Documents/ml_spark/python_test/PyArrow/venv/bin/python
examples/flight/server.py --port 2000
Serving on grpc+tcp://localhost:2000
Then I started client below:
/Users/user/Documents/ml_spark/python_test/PyArrow/venv/bin/python client.py
get localhost:2000 -c foo
Got error with _flight.pyx
File "client.py", line 188, in <module>
main()
File "client.py", line 184, in main
commands[args.action](args, client, connection_args)
File "client.py", line 91, in get_flight
info = client.get_flight_info(descriptor)
File "pyarrow/_flight.pyx", line 1527, in
pyarrow._flight.FlightClient.get_flight_info
File "pyarrow/_flight.pyx", line 78, in pyarrow._flight.check_flight_status
File "pyarrow/error.pxi", line 119, in pyarrow.lib.check_status
pyarrow.lib.ArrowKeyError: 'Flight not found.'. Detail: Python exception:
KeyError
Added some printed lines prior to line at line 91:
info = client.get_flight_info(descriptor)
Run it again, appears command and args and descriptor are all right,
get_flight_info failed.
(venv) user@users-MBP flight %
/Users/user/Documents/ml_spark/python_test/PyArrow/venv/bin/python
client_print.py get localhost:2000 -c foo
******args are Namespace(action='get', command='foo', host='localhost:2000',
mtls=None, path=None, tls=False, tls_roots=None) detail is get
******connection_args is {}
descriptor is <pyarrow.flight.FlightDescriptor cmd=b'foo'>
Traceback (most recent call last):
File "client_print.py", line 192, in <module>
main()
File "client_print.py", line 188, in main
commands[args.action](args, client, connection_args)
File "client_print.py", line 92, in get_flight
info = client.get_flight_info(descriptor)
File "pyarrow/_flight.pyx", line 1527, in
pyarrow._flight.FlightClient.get_flight_info
File "pyarrow/_flight.pyx", line 78, in pyarrow._flight.check_flight_status
File "pyarrow/error.pxi", line 119, in pyarrow.lib.check_status
pyarrow.lib.ArrowKeyError: 'Flight not found.'. Detail: Python exception:
KeyError
I use the code as is in examples.
Thanks
George
