Description

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.
