Steve Loughran created YARN-4264: ------------------------------------ Summary: In-VM test ATS instances fail with metrics already registered Key: YARN-4264 URL: https://issues.apache.org/jira/browse/YARN-4264 Project: Hadoop YARN Issue Type: Bug Components: timelineserver Affects Versions: 2.8.0 Reporter: Steve Loughran
Testing my SPARK-1537 code against branch-2 triggers stack traces due to failed attempts to re-register metrics. This is with code which works against 2.7.1, so it's a regression. Either the timeline server needs to unregister its metrics on shutdown, or ATS adds an option to disable metrics for test purposes. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
