Review Comment:
Yea, during my testing, if stop() canceled the cancellationToken, it would
result in some strange behavior, GetOperationStatus issues causing
CloseOperation to fail.
I think it is because in THTTPTransport, a new Stream is created when the
request is flushed:
https://github.com/apache/thrift/blob/master/lib/netstd/Thrift/Transport/Client/THttpTransport.cs#L281
In the proxy logs, I remember seeing requests sent out with
GetOperationStatus and CloseOperationStatus while testing another PR
I think we are safe in HiveServer2Statement, but we might need to adjust
CancellationToken in DatabricksReader, CloudFetchResultFetcher, and
DatabricksCompositeReader
