------------------------------------
Summary: Airflow should not store logs as raw ISO timestamps
Key: AIRFLOW-2158
URL: https://issues.apache.org/jira/browse/AIRFLOW-2158
Project: Apache Airflow
Issue Type: Improvement
Environment: 1.9.0
Reporter: Christian D
Fix For: Airflow 2.0
Problem:
When Airflow writes logs to disk, it uses a ISO-8601 timestamp as the filename.
In a Linux filesystem this works completely fine (because all characters in a
ISO-8601 timestamp is allowed). However, it doesn't work on Windows based
systems (including Azure File Storage) because {{:}} is a disallowed character.
Solution:
Ideally, Airflow should store logs such that they're somewhat compatible across
file systems. An easy way of fixing this would therefore be to always replace
{{:}} with underscores.
