What happened there the parallell command started and completed immediately
- likely there is a typo somewhere that make the script failed and it did not
have chance to show output. The output should be printed if the scripts fail,
but in this case I think they failed with some typo/error before they had a
change to set a trap that save status to status file
In this case just remove the redirection of parallell command (in
kind::run_kubernetes_tests):
```
parallel --ungroup --bg --semaphore --semaphorename "${SEMAPHORE_NAME}" \
--jobs "${MAX_PARALLEL_K8S_JOBS}" \
"$(dirname "${BASH_SOURCE[0]}")/${single_job_filename}" \
"${kubernetes_version}" "${python_version}" >"${JOB_LOG}"
2>&1
```
change this to:
```
parallel --ungroup --bg --semaphore --semaphorename "${SEMAPHORE_NAME}" \
--jobs "${MAX_PARALLEL_K8S_JOBS}" \
"$(dirname "${BASH_SOURCE[0]}")/${single_job_filename}" \
"${kubernetes_version}" "${python_version}"
```
And you should see the error
UPDATE: The solution below is better and can be a long term change that can
stay.
