Li Lu commented on YARN-4183: ----------------------------- bq. Already Subtask YARN-3623 is raised for this, hope i can work on this ? Let's fix the config problem raised in YARN-3623 here since it's no longer a ATS v2 problem. Please feel free to open a new JIRA for the API fix in YARN-2928. If you happen to have cycles feel free to assign it to you. [~sjlee0] any suggestions here? Thanks! > Enabling generic application history forces every job to get a timeline > service delegation token > ------------------------------------------------------------------------------------------------ > > Key: YARN-4183 > URL: https://issues.apache.org/jira/browse/YARN-4183 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.7.1 > Reporter: Mit Desai > Assignee: Mit Desai > Fix For: 3.0.0, 2.8.0, 2.7.2 > > Attachments: YARN-4183.1.patch > > > When enabling just the Generic History Server and not the timeline server, > the system metrics publisher will not publish the events to the timeline > store as it checks if the timeline server and system metrics publisher are > enabled before creating a timeline client. > To make it work, if the timeline service flag is turned on, it will force > every yarn application to get a delegation token. > Instead of checking if timeline service is enabled, we should be checking if > application history server is enabled. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
