Mit Desai created YARN-4183: ------------------------------- Summary: 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
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)
