Joe McDonnell updated IMPALA-11250:
-----------------------------------
Component/s: Backend
Affects Version/s: Impala 4.1.0
Description:
On Ubuntu 20, the test consistently fails with this messages:
{noformat}
/home/impdev/Impala/be/src/util/webserver-test.cc:393
Value of: num_negotiate_failure
Actual: 2
Expected: negotiate_failure_metric->GetValue()
Which is: 1{noformat}
This code location is expecting curl to try without authentication, fail, then
retry with authentication. Based on the curl logs, on Ubuntu 20 it just starts
with authentication. This seems like a change in behavior for curl.
We can narrow down which curl version changed the behavior, detect the curl
version, and change the test according to the different behaviors.
Alternatively, if toolchain curl was built with SPNEGO support, we could use
that on all platforms.
