[jira] [Assigned] (YARN-8383) TimelineServer 1.5 start fails with
NoClassDefFoundError
[ https://issues.apache.org/jira/browse/YARN-8383?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jason Lowe reassigned YARN-8383:
--------------------------------
Assignee: Jason Lowe
Attaching a patch for branch-2.8 that also shades the fst jar so it gets the jackson rewrites. I manually tested that the ATSv1.5 timeline server can boot after this change when it could not before.
I'm wondering if we should remove the shading in branch-2 and branch-2.9. The reason this works in those branches is because fst happens to pick up the proper jackson version from HDFS dependencies rather than the YARN ones. If HDFS changes its dependencies this could break again, so I'm tempted to just let the dependency go unshaded in 2.9+. Thoughts?
