Liyin Liang updated YARN-647:
-----------------------------

    Fix Version/s: 2.2.1

> historyServer can't show container's log when aggregation is not enabled
> ------------------------------------------------------------------------
>
>                 Key: YARN-647
>                 URL: https://issues.apache.org/jira/browse/YARN-647
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: documentation
>    Affects Versions: 0.23.7, 2.0.4-alpha
>         Environment:  yarn.log-aggregation-enable=false , HistoryServer will show like this:
> Aggregation is not enabled. Try the nodemanager at hd13-vm1:34669
>            Reporter: shenhong
>             Fix For: 2.2.1
>
>         Attachments: 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.
