------------------------------------
Summary: [YARN] New feature: custom log URL for stdout/stderr
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
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.
