### Current Status
- Current version of Timeline sever has been completed. Essential functionality of the timeline server can work in both secure and non secure modes. The generic history service is also ridden on the timeline store. In subsequent releases we will be rolling out next generation timeline service which is scalable and reliable. Finally, the Application specific information is only available via RESTful APIs, using JSON type content - ability to install framework specific UIs in YARN isn't supported yet.
