Thanks for the report, but repeating these steps does not lead to above mentioned error in my case. I simply get.

opendir failed for /tmp/a: Permission denied

I'll surely investigate it later, but could you provide some info about your setup?

What system do you have?
(uname -a, lsb_release -drc)
What gcc version have you used for building metastore?
(gcc -v)
Do you use any custom FLAGS during build?
(set | grep FLAGS=)
What libc implementation and version are you using?
What filesystem do you use and how it is mounted?
(mount | grep $(df /tmp | awk 'NR==2{print$1}'))

I was able to reproduce this using the following steps:

mkdir /tmp/a
touch /tmp/a/foo
setfattr -n user.foo -v foo /tmp/a/foo           
chmod 000 /tmp/a/foo
metastore -s /tmp/a/

Thank you, @dfandrich, for refined reproduction steps.
I'll look into it this week.
