Robert Joseph Evans commented on MAPREDUCE-2677: ------------------------------------------------ You are right. I do not know how I missed that. I think it must have been a merge issue or something, because I tested it before submitting the patch the first time. I can add in an about page without too much work. HsController and HistroyContext still need to extend AppController and AppContext until the UI is completely separate. There are still pages that are coming from the ApplicationMaster UI. But I will look into doing that for MR-2675. > MR-279: 404 error while accessing pages from history server > ----------------------------------------------------------- > > Key: MAPREDUCE-2677 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2677 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2 > Affects Versions: 0.23.0 > Reporter: Ramya Sunil > Assignee: Robert Joseph Evans > Fix For: 0.23.0 > > Attachments: MR-2677-V2.patch, MR-2677-trunk-V3.patch, > MR-2677-trunk-V4.patch, MR-2677-trunk-V5.patch, MR-2677-v1.txt > > > Accessing the following pages from the history server, causes 404 HTTP error > 1.
