Haibo Chen commented on YARN-5765:
----------------------------------

Sorry [~Naganarasimha], did not mean to dismiss your solution. Assigning this to you since you have got a working solution. Let's resolve this blocker. Ideally, I still prefer to make changes to mkdirs() which all directory creations have to call.

> 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.
