Gopal V commented on TEZ-3422:
------------------------------
bq. this application user should not have u+x on the root directory
If the "/" isn't a+x that's a problem ( that's the equivalent of "chmod 0666
/" on linux - do not try this, the system will be bricked).
> TEZ performs EXECUTE on / (root directory)
