I seem to be getting this same problem as the issue https://github.com/elastic/rally/issues/472 with esrally 1.4.1 and 2.0.0
esrally --pipeline benchmark-only --track=nyc_taxis --challenge append-no-conflicts-index-only --target-hosts=https://a.b.c.d:30537 --client-options="use_ssl:true,basic_auth_user:'admin',basic_auth_password:'admin',verify_certs:false"
I'm getting:
[ERROR] Cannot race. Error in race control (ConnectionError([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)) caused by: SSLError([SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:852)))
There should be no verification at all so why is this showing up ?
