The new UI will co-exist with the old YARN UI, by default it is disabled. Please refer to User documentation of the new YARN UI <https://github.com/apache/hadoop/blob/YARN-3368/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-site/src/site/markdown/YarnUI2.md> for more details. In addition, There’re two working-in-progress features need the new UI to be merged to trunk for further development. 1) UI of YARN Timeline Server v2 (YARN-2928) 2) UI of YARN ResourceManager Federation (YARN-2915). *Status of YARN next generation web UI* Completed features - Cluster Overview Page - Scheduler page - Applications / Application / Application-attempts pages - Nodes / Node page Integration to YARN - Hosts new web UI in RM - Integrates to maven build / package Miscs: - Added dependencies to LICENSE.txt/NOTICE.txt - Documented how to use it. (In hadoop-yarn-project/hadoop-yarn/hadoop- yarn-site/src/site/markdown/YarnUI2.md) Major items will finish on trunk: - Security support We have run the new UI in our internal cluster for more than 3 months, lots of people have tried the new UI and gave lots of valuable feedbacks and reported suggestions / issues to us. We fixed many of them so now we believe it is more ready for wider folks to try. Merge JIRA for Jenkins is: https://issues.apache.org/jira/browse/YARN-4734.
