> Key: YARN-647
> URL: https://issues.apache.org/jira/browse/YARN-647
> Project: Hadoop YARN
> Issue Type: Improvement
> Affects Versions: 0.23.7, 2.0.4-alpha, 2.2.0
> Environment: yarn.log-aggregation-enable=false , HistoryServer will
> show like this:
> Aggregation is not enabled. Try the nodemanager at hd13-vm1:34669
> Reporter: shenhong
> Assignee: shenhong
> Attachments: yarn-647-2.patch, yarn-647.patch

>
> When yarn.log-aggregation-enable is seted to false, after a MR_App complete,
> we can't view the container's log from the HistoryServer, it shows message
> like:
> Aggregation is not enabled. Try the nodemanager at hd13-vm1:34669
> Since we don't want to aggregate the container's log, because it will be a
> pressure to namenode. but sometimes we also want to take a look at
> container's log.
> Should we show the container's log across HistoryServer even if
> yarn.log-aggregation-enable is seted to false.
