> `airflow run` config doens't cope with % in config values.
> ----------------------------------------------------------
>
> Key: AIRFLOW-3178
> URL: https://issues.apache.org/jira/browse/AIRFLOW-3178
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Ash Berlin-Taylor
> Assignee: Ash Berlin-Taylor
> Priority: Major
> Fix For: 1.10.1
>
>
> ConfigParser uses %-signs for interpolation, so if you need a literal % in
> airflow.cfg it needs to be escaped in by specifying them as {{%%}}), but by
> the time they are written out to the temporary config that is passed to
> `airflow run` they escaping is lost.
> This is also true for configuration via environment variables, where {{%}}
> doesn't need to be escaped at all, but is included (sometimes needlessly) in
> the config un-escaped.
