> I have started a flight's local python server with TLS support using the
> testing certificates present in repo:
> {code:java}
> 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{code}
> 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:
> {code:java}
> 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{code}
> File iris.csv is pushed successfully.
> 2. List the flights available on the server
> {code:java}
> python3 <arrow_dir>/python/examples/flight/client.py list --tls --tls-roots
> <arrow_dir>/testing/data/flight/root-ca.pem localhost:5005{code}
> 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
> {code:java}
> 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{code}
> It is failing with following errors:
> {quote}Ticket: <Ticket b"(1, None, (b'/sharedFolder/dataset/iris.csv',))">
