aeroyorch opened a new pull request, #69090:
URL: https://github.com/apache/airflow/pull/69090
Running task logs were not shown in the airflow UI when using elasticsearch
remote
logging, and only appeared once the task had finished. In Airflow 3 the
supervisor
uploads logs to elasticsearch only after the task finishes, and the
elasticsearch
handler reads only from elasticsearch, so a running task had nothing to
display.

**Fix:**
For airflow 3, running and deferred tasks (current attempt) now delegate to
the base
`FileTaskHandler._read`, which serves the live worker and executor logs and
drives
`end_of_log` from the task state, similar to what is done by the S3/GCS
backends.
