Description

Various RPCs converted to KRPC recently mistakenly pass the resolved IP address instead of the actual hostname. An example below in coordinator-backend-state.cc. This may lead to failure when running with Kerberos enabled.

  std::unique_ptr<ControlServiceProxy> proxy;
  Status get_proxy_status =
      ControlService::GetProxy(krpc_host_, krpc_host_.hostname, &proxy);
  if (!get_proxy_status.ok()) {
    SetExecError(get_proxy_status);
    return;
  }
