-------------------------------------

Definitely a blocker for 2.8 as well. cc [~naganarasimha_gr@apache.org] and [~Ying Zhang] who worked on YARN-5287.

> LinuxContainerExecutor creates usercache/\{userId\}/appcache/\{appId\} with wrong group owner, causing Log aggregation and ShuffleHandler to fail because node manager process does not have permission to read the files under the directory.
> This can be easily reproduced by enabling LCE and submitting a MR example job.
