Subject Bug Report:grpc tls assertion failed when using pyarrow(2.0.0) flight client get data
Date Fri, 20 Nov 2020 07:36:01 GMT
Hello,
When I using pyarrow flight client get remote data, I encounter the "assertion failed" problem:
[cid:38F65524-75DE-4C9A-9D57-2D857AA1503D@sankuai.info]

It seems the grpc bug. And it is similar with the previous problem: https://issues.apache.org/jira/browse/ARROW-7689
.
And the record of grpc is : https://github.com/grpc/grpc/issues/20311

In my project, the version of pyarrow is 2.0.0, and the version of grpcio is 1.33.2. Both
are the latest version.
[cid:ED9104BF-37F5-4663-947B-BE4D66917F1E@sankuai.info] [cid:AF8FB7E3-A66D-4579-8AE6-8B14C8F912D9@sankuai.info]

When I change the version of pyarrow from 2.0.0 to 0.17.1, the problem disappeared.

I am confused why the latest version of pyarrow will cause the bug? And the old version will
not?
Is this a bug?

Thanks a lot.
