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?
