xiaozilong commented on FLINK-20526:
------------------------------------
The configuration scan is enabled by default for logback and default scan
interval is 1 min. So we only changed the scan default value to 30s actually
for logback. I think we can submit a new issue if there are users feedback the
problem as you mentioned. What do you think? [~chesnay]
