The KDC in this case is the "minikdc" from
https://github.com/apache/impala/blob/master/be/src/kudu/security/test/mini_kdc.cc.
I see evidence of it, and have been able to look at its configuration by,
um, adding --gtest_break_on_failure. (The feature actually doesn't work,
presumably because of an interaction with breakpad, but a temporary
directory is left on my filesystem, so that's nice.)
