Issue #143 added a check to detect if Cloudera will be impacted by spn alias uniqueness issue if enabling kerberos using Microsoft AD. However, MS introduced another patch to address this issue which breaks the way the prereq-check script tests for the spn alias uniqueness.
The spn uniqueness tests should be updated to use an existing cloudera hostname instead of randomly generating hostname. E.g. when running the script, use the hostname of the host the script is running on.
