-------------------------------------
[~snemeth], Please take this and help me solve this issue
> Yarn log aggregation of spark streaming job
> -------------------------------------------
>
> Key: YARN-8818
> URL: https://issues.apache.org/jira/browse/YARN-8818
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Ayush Chauhan
> Priority: Major
>
> By default, YARN aggregates logs after an application completes. But I am
> trying to aggregate logs for spark streaming job which in theory will run
> forever. I have set the following properties for log aggregation and
> restarted yarn by restarting {{hadoop-yarn-nodemanager}} for core & task
> nodes and {{hadoop-yarn-resourcemanager}} for master node on my emr cluster.
> I can view my changes in [http://node-ip:8088/conf].
> {noformat}
> yarn.log-aggregation-enable => true{noformat}
> {noformat}
> yarn.log-aggregation.retain-seconds => 172800{noformat}
> {noformat}
> yarn.log-aggregation.retain-check-interval-seconds => -1 {noformat}
> {noformat}
> yarn.nodemanager.log-aggregation.roll-monitoring-interval-seconds =>
> 3600{noformat}
> All the articles and resources have only mentioned to include
> {{yarn.nodemanager.log-aggregation.roll-monitoring-interval-seconds}}
> property and yarn will start aggregating logs for running jobs. But it is not
> working in my case.
