These tests failed in various ways depending on OS/openssl version. An issue identified is that the certificates contained CN=* while wildcard subject should be like *.<domain>. Recreated wildcard certs with *.impala.test common name and added some host names that match them in bootstrap_system.sh. Removed the @xfail from the tests as my expectation is that they should work on all supported OS. Tested on - Ubuntu 20.04 / OpenSSL 1.1.1f - Ubuntu 22.04 / OpenSSL 3.0.2 - RHEL 7.9 / OpenSSL 1.0.2k - RHEL 8.6 / OpenSSL 1.1.1k - Rocky 9.2 / OpenSSL 3.2.2 Change-Id: Ieedf682d06bdb6f8f68a5f77e41175e895b77ca9 Reviewed-on: http://gerrit.cloudera.org:8080/22569 Reviewed-by: Riza Suminto <riza.suminto@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
