             Summary: Localhost connections to single-host clusters on Ubuntu don't skip TLS
                 Key: KUDU-1900
                 URL: https://issues.apache.org/jira/browse/KUDU-1900
             Project: Kudu
          Issue Type: Bug
          Components: perf, security
            Reporter: Todd Lipcon


On Ubuntu, it seems like we sometimes end up with connections from 127.0.1.1 to 127.0.0.1 when running a local cluster and connecting to to it from the same machine. This is because Ubuntu puts an entry with the host's external hostname in /etc/hosts as 127.0.1.1, and the tablet server ends up registering with that name. The code that detects loopback connections sees the "127.0.0.1 -> 127.0.1.1" and decides it's not loopback.
