-------------------------------
Summary: [FlightRPC][C++] DoPutPayloadWriter doesn't always expose
server error message
Key: ARROW-8160
URL: https://issues.apache.org/jira/browse/ARROW-8160
Project: Apache Arrow
Issue Type: Bug
Components: C++, FlightRPC
Affects Versions: 0.16.0
Reporter: David Li
{noformat}
C:/projects/arrow/cpp/src/arrow/flight/flight_test.cc(1261): error: Value of:
status.message()
Expected: has substring "Invalid token"
Actual: "Could not write record batch to stream: "
[ FAILED ] TestBasicAuthHandler.FailUnauthenticatedCalls (17 ms)
{noformat}
This happens because {{Close()}} calls {{RecordBatchPayloadWriter::Close()}},
which calls {{CheckStarted}}, which in turn tries to write data. If the data
gets flushed and the server responds in time, we'll see a failure during
writing, causing us to never check the server status (which is the last part of
{{DoPutPayloadWriter::Close}}). We need to reliably check and expose the gRPC
status.
