According to the docs ansible is expected to return 3 if there were unreachable nodes. Zuul reacts on this and retries the job. However ansible really returns 4 in this case [1] which actually is the code for a parse error (which doesn't make sense to retry). To work around that add a simple callback plugin that gets notified if there are unreachable nodes and write the information about which nodes failed to a special file beneath the job-output.txt. The executor can detect this and react properly then. Further we have the information about which nodes failed in this file which gets uploaded to the log server too if it exists.

Python Version Support
Zuul v3 requires Python 3. It does not support Python 2.
As Ansible is used for the execution of jobs, it's important to note
that while Ansible does support Python 3, not all of Ansible's modules
do. Zuul currently sets ansible_python_interpreter to
python2 so that remote content will be executed with Python 2.
