Jason Lowe commented on YARN-171:
---------------------------------
It's already doing this for AM logs today off of the RM app page, correct? I
remember seeing redirect-to-HS support in the NM webapp pages.
> NodeManager should serve logs directly if log-aggregation is not enabled

> Key: YARN-171
> URL: https://issues.apache.org/jira/browse/YARN-171
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 0.23.3
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Siddharth Seth
>
> NodeManagers never serve logs for completed applications. If log-aggregation
> is not enabled, in the interim, due to bugs like YARN-162, this is a serious
> problem for users as logs are necessarily not available.
> We should let nodes serve logs directly if
> YarnConfiguration.LOG_AGGREGATION_ENABLED is set. This should be okay as
> NonAggregatingLogHandler can retain logs upto
> YarnConfiguration.NM_LOG_RETAIN_SECONDS.
