Description
I have started a flight's local python server with TLS support using the testing certificates present in repo:
python3 <arrow_dir>/python/examples/flight/server.py --host localhost --tls <arrow_dir>/testing/data/flight/cert0.pem <arrow_dir>/testing/data/flight/cert0.key
This server is started successfully.
Now I started testing the python client with TLS support.
1. Client pushing a csv file to the flightendpoint server:
python3 <arrow_dir>/python/examples/flight/client.py put --tls --tls-roots <arrow_dir>/testing/data/flight/root-ca.pem localhost:5005 /sharedFolder/dataset/iris.csv
File iris.csv is pushed successfully.
2. List the flights available on the server
python3 <arrow_dir>/python/examples/flight/client.py list --tls --tls-roots <arrow_dir>/testing/data/flight/root-ca.pem localhost:5005
It is listing the flight which is pushed in above step 1.
3. Get/Retrieve the specific flight(eg. /sharedFolder/dataset/iris.csv) from the server
python3 <arrow_dir>/python/examples/flight/client.py get --tls --tls-roots <arrow_dir>/testing/data/flight/root-ca.pem -p /sharedFolder/dataset/iris.csv localhost:5005
It is failing with following errors:
Ticket: <Ticket b"(1, None, (b'/sharedFolder/dataset/iris.csv',))">
<Location b'grpc+tls://localhost:5005'>
