Haibo Chen updated YARN-5765:
-----------------------------
Description:
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.
