Exception: Problem with accessing api. Reason: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:579)>

Root cause: starting from python 2.7.9, python will validate the SSL certificate by default and if no valid SSL certificate is configured it might fail. All the python version below 2.7.9 this is disabled by default.

More Details can be found in this JIRA :

the above JIRA is fixed in ambari-2.7 version so all the versions below ambari-2.7 and having python 2.7.9 will be having this issue.

Workaround :

The fix of JIRA : AMBARI-23893 is this :

We can actually take backup of file : /var/lib/ambari-server/resources/scripts/ and use this instead .


1) Navigate to /var/lib/ambari-server/resources/scripts/

cd /var/lib/ambari-server/resources/scripts/

2) take Backup of

mv configs.py_Backup

3) wget the raw github content with fix:


4) give necessary permissions

chmod -R 750

5) Retry the Operation with --unsafe option 

[root@asnaik1 certs]# /var/lib/ambari-server/resources/scripts/ --port=8443 --action=set --host=asnaik1.openstacklocal --cluster=asnaik --config-type=kafka-env --user=admin --password=admin --key=kafka_log_dir --value=/tmp --protocol=https --unsafe 


NOTE: Remember to add --unsafe option as that was the change associated with the apache-jira
