> Earlier fix for YARN-5287 has been reverted due to this issue : 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.
