#   KerberosAuthProvider::RunKinit() - and there may be other difficulties
#   down the road with getting all the permissions correct.
# - Futher Beeline -> HiveServer2 -> HBase|MapReduce combo issues
# - Getting farther down the testing path, it's likely more issues will turn up
# - Further extensive testing
