>    Affects Versions: 2.8.0, 3.0.0-alpha1

> 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 as a user that does not belong to the same group that NM process belongs to.
