IMHO we can't go with approach #20326 went since cluster ID is not available
in default log URL so cannot retrieve. Also for me relying on pattern
(`container_`) in URL feels fragile: while #20326 only extracted container ID
from URL, we need to get some other parameters as well, which opens bigger
possibility to be broken.

> ----------------------------------------------------
>
> Key: SPARK-26311
> URL: https://issues.apache.org/jira/browse/SPARK-26311
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 2.4.0
> Reporter: Jungtaek Lim
> Priority: Major
>
> Spark has been setting static log URLs for YARN application, which points to
> NodeManager webapp. Normally it would work for both running apps and finished
> apps, but there're also other approaches on maintaining application logs,
> like having external log service which enables to avoid application log url
> to be a deadlink when NodeManager is not accessible. (Node decommissioned,
> elastic nodes, etc.)
> Spark can provide a new configuration for custom log url on YARN mode, which
> end users can set it properly to point application log to external log
> service.
