This is not a SSL related issue. For, RHEL 6.7, need RHEL 6 repo:
https://archive.cloudera.com/p/cdh5/redhat/6/x86_64/cdh/5.16.2/
// you are using the RHEL7 repo.

Can you check a few things from the YUM/OS side:

1. Are you behind firewall/proxy?

2.  Are you able to access any other public repos?

3. Try,

     # yum clean all

     # yum repolist -v

Important notice: The support for CDH 5.16.x ended on December 2020. refer: https://www.cloudera.com/legal/policies/support-lifecycle-policy.html
