Setting up Airflow remote logs to S3 bucket

Today is a short one, but hopefully a valuable devOps tip, if you are currently setting up remote logging integration to S3 of Airflow logs using Airflow version 1.9.0.

Basically this stackoverflow post provides the main solution. However, the current template incubator-airflow/airflow/config_templates/airflow_local_settings.py present in master branch contains a reference to the class “airflow.utils.log.s3_task_handler.S3TaskHandler”, which is not present in apache-airflow==1.9.0 python package. The fix is simple – use rather this base template: https://github.com/apache/incubator-airflow/blob/v1-9-stable/airflow/config_templates/airflow_local_settings.py (and follow all other instructions in the mentioned answer)

Hope this helps!
