[jira] [Created] (YARN-6323) Rolling upgrade/config change is
broken on timeline v2.

---------------------------
Summary: Rolling upgrade/config change is broken on timeline v2.
Key: YARN-6323
URL: https://issues.apache.org/jira/browse/YARN-6323
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Li Lu
Found this issue when deploying on real clusters. If there are apps running when we enable timeline v2 (with work preserving restart enabled), node managers will fail to start due to missing app context data. We should probably assign some default names to these "left over" apps. I believe it's suboptimal to let users clean up the whole cluster before enabling timeline v2.
