Subject Re: [DISCUSS] Looking to a 2.8.0 release
Date Wed, 25 Nov 2015 19:08:18 GMT
This is the current state from the feedback I gathered.
 - Support priorities across applications within the same queue YARN-1963
    — Can push as an alpha / beta feature per Sunil
 - YARN-1197 Support changing resources of an allocated container:
    — Can push as an alpha/beta feature per Wangda
 - YARN-3611 Support Docker Containers In LinuxContainerExecutor: Well most of it anyways.
    — Can push as an alpha feature.
 - YARN Timeline Service v1.5 - YARN-4233
    — Should include per Li Lu
 - YARN Timeline Service Next generation: YARN-2928
    — Per analysis from Sangjin, drop this from 2.8.

One open feature status
 - HDFS-8155    Support OAuth2 in WebHDFS: Alpha / Early feature?

Updated the Roadmap wiki with the same.
