URL: https://github.com/apache/hadoop/pull/6053
YARN-11567 - Aggregate container launch debug artifacts automatically in
case of error
- create new feature flag:
yarn.nodemanager.log-container-debug-info-on-error.enabled
- default: false
- if true, the feature records debug artifact for non-zero exit codes
- If yarn.nodemanager.log-container-debug-info.enabled is true, it does not
have effect on the behavior.

> Priority: Minor

> In cases where a container fails to launch without writing to a log file, we
> often would want to see the artifacts captured by
> {{yarn.nodemanager.log-container-debug-info.enabled}} in order to better
> understand the cause of the exit code. To enable this feature for every
> container maybe over kill, so we need a feature flag to capture these
> artifacts in case of errors.
