Eric Badger commented on YARN-7344:
-----------------------------------
Looks like the problem here is that realpath for {{/bin}} returns {{/usr/bin/}}
on CentOS7/RHEL7. So when the test checks for the permitted mounts, it sees
{{/usr/bin/ls}} or {{/usr/bin}} instead of {{/bin/ls}} or {{/bin}}
{noformat}
[ebadger@foobar]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.1 (Maipo)
[ebadger@foobar]$ realpath /bin
/usr/bin
[ebadger@foobar]$ realpath /bin/ls
/usr/bin/ls
