Hi all,
I am trying to manage a connection to the `flight server` via `pyarrow`
library and encountered below problem:
```python
Traceback (most recent call last):
File "...", line 22, in <module>
"grpc+tls://some_address:9443", disable_server_verification=True)
File "pyarrow/_flight.pyx", line 1047, in
pyarrow._flight.FlightClient.__init__
File "pyarrow/_flight.pyx", line 1093, in pyarrow._flight.FlightClient.init
File "pyarrow/_flight.pyx", line 80, in pyarrow._flight.check_flight_status
File "pyarrow/error.pxi", line 105, in pyarrow.lib.check_status
pyarrow.lib.ArrowNotImplementedError: Using encryption with server
verification disabled is unsupported. Please use a release of Arrow Flight
built with gRPC 1.27 or higher.
```
I am using something similar to this:
```python
from pyarrow import flight
import pyarrow as pa
class TokenClientAuthHandler(flight.ClientAuthHandler):
"""An example implementation of authentication via handshake."""
def __init__(self):
super().__init__()
self.token = bytes('Bearer ' + token, 'utf-8')
def authenticate(self, outgoing, incoming):
outgoing.write(self.token)
self.token = incoming.read()
def get_token(self):
return self.token
read_client = flight.FlightClient(
"grpc+tls://some_address:9443", disable_server_verification=True)
```
The same code on `Ubuntu` linux is working fine.
Here are package versions that I am using:
- `pyarrow==3.0.0`
- `grpcio==1.35.0`
- `grpc-cpp==1.35.0`
My environment is `conda`, `3.6 / 3.7`
I'v tried to change/adjust these versions somehow but with no success.
Maybe you will know what cause the problem as I cannot find anything besides
this thread: https://www.mail-archive.com/[email protected]/msg21050.html
I will appreciate your answers!
