I think your problem is exactly what Jay SenSharma addressed

As you using Python version "python-2.7.5" or higher, hence you should try to either downgrade the python version to lower than python-2.7.5 as it causes this issue.

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)<br>

(OR)
Else you will need to following the steps mentioned in the following doc to fix the "certificate verify failed (_ssl.c" issue while using RHEL7: Controlling and troubleshooting certificate verification
https://access.redhat.com/articles/2039753#controlling-certificate-verification-7

Also we will suggest you to remove the Ambari Server certificates as mentioned in the following doc so that new certificates can be generated by ambari.

@Florin Miron,

Run the below command on all the ambari agent nodes. Quick and easy

sed -i 's/verify=platform_default/verify=disable/'/etc/python/cert-verification.cfg

Thanks,
