Ying Zhang commented on YARN-5287:
----------------------------------
Hi Naganarasimha, I've uploaded a new patch with a new test case included. I've
run the "test-container-executor" with regular user and root. It passes.
As I said earlier, there is issue with the current test-container-executor when
running under root. I have made some minor change to make it pass(to be
specific, in test-container-executor.c, in function main(), when running as
root, test_recursive_unlink_children() needs to be run before
set_user(username). Not sure if it is correct, just a work-around). I don't
think I should include it in this patch. Let me know your idea. Thank you.

> LinuxContainerExecutor fails to set the proper permissions on the local
> directories(i.e., /hadoop/yarn/local/usercache/... by default) if the cluster
> has been configured with a restrictive umask, e.g.: umask 077. Job failed due
> to the following reason:
> Path /hadoop/yarn/local/usercache/ambari-qa/appcache/application_xxxxxxxx has
> permission 700 but needs permission 750
