incubator-airflow git commit: [AIRFLOW-1018] Make processor use
logging framework
Repository: incubator-airflow
Updated Branches:
refs/heads/master 4fb7a90b3 -> 4ee4e474b
[AIRFLOW-1018] Make processor use logging framework
Until now, the dga processor had its own logging
implementation,
making it hard to adjust for certain use cases
like working
in a container.
This patch moves everything to the standard
logging framework.
Closes #2728 from bolkedebruin/AIRFLOW-1018
