We experienced a similar issue after upgrading from 1.10.3 to 1.10.9: no
more task logging visible in the UI. In our case it was specifically for the
KubernetesPodOperator, but not for the BashOperator for instance. We fixed it
by adding a logger for the airflow.contrib package (in the main airflow logging
configuration file, see snippet below), since the KubernetesPodOperator lives
there. So if the operator you're missing logs from is also from the contrib
package, you can try this fix to see if it re-appears. Probably it also works
for other operators, as long as you specify the right package they are in as
extra logger.
My guess is that the combination of forking instead of starting a whole new
process + having no specific logger for the package triggered this particular
issue.
Added log config snippet:
```
'airflow.contrib': {
'handlers': bucket_handler,
'level': LOG_LEVEL,
'propagate': True,
}
```
