Ash Berlin-Taylor commented on AIRFLOW-4719:
--------------------------------------------
Do you have any symlinks in that path somewhere? Do you have any refrence to
{{opt}} in your config file anywhere? (or in the env that Airflow is running in)
> Scheduler: 'airflow scheduler' fails to make opt directory

> Key: AIRFLOW-4719
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4719
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 1.10.3
> Environment: In a fedora 29 Singularity container
> Reporter: Robert Lugg
> Priority: Major
>
> I have a strange error when running `airflow schedule`. Python errors with:
> `Process DagFileProcessor0-Process:

> That very last line shows the problem.
> Airflow is attempting to make a directory one level down from the directory I
> own. `/remote/XXX/rlugg` is my directory, but `/remote/XXX` is not.
> I use AIRFLOW_HOME to point to
> `/remote/XXX/rlugg/machine_learning/20190530_airflow_learn2/airflow`
> I've tried changing airflow.cfg as well as setting the environment variable
> `export AIRFLOW___CORE___BASE_LOG_FOLDER=/x/y/z` yet the same error (with the
> exact same directory) is shown.
> I am running within a Singularity container if that's relevant.
