---------------------------------
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.
