>
> Key: YARN-6767
> URL: https://issues.apache.org/jira/browse/YARN-6767
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineclient
> Affects Versions: 3.0.0-alpha4
> Reporter: Haibo Chen
> Assignee: Vrushali C
> Priority: Major
>
> As discussed in the call, when an application first starts to run, its
> corresponding TimelineCollector instance may not be up yet, or if the
> TimelineCollector goes down when node manager dies (TimelineCollector now
> runs as part of NM auxiliary services), the timeline client
> will not able to write entities. We need to address or mitigate the issue if
> possible, or at least call it out.
