Description

When initializing the FlightClient I get the following error message:

ArrowNotImplementedError: Using encryption with server verification disabled is unsupported. Please use a release of Arrow Flight built with gRPC 1.27 or higher.

Traceback:

 

Verions: Python 3.9.5

# Name                    Version                   Build  Channel
arrow-cpp                 5.0.0           py39h037c299_3_cpu    conda-forge

Code is similar to:

import pandas
from pyarrow import flight

class XYZClient():    
    __scheme = "grpc+tls"
    __token = None
    __flightclient = None    
    
    def __init__(self, username, password, hostname="some-host", flightport=32010):
        flight_client = flight.FlightClient(
            "{}://{}:{}".format(self.__scheme, hostname, flightport),
            middleware=[DremioClient.DremioClientAuthMiddlewareFactory()],
            disable_server_verification=True
        )
        self.__token = flight_client.authenticate_basic_token(
            username, password)
        self.__flightclient = flight_client

There has been a similar issue (https://issues.apache.org/jira/browse/ARROW-11695#) for an earlier version of pyarrow that has been marked as resolved.
