Comment 2 for bug 1490670

I've also ran into this issue in a devstack environment. It appears that /etc/tempest/ doesn't exist, which may lead the exception.

Steps to reproduce:
1. stack.sh with local.conf:
[[local|localrc]]
ADMIN_PASSWORD=password
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=a682f596-76f3-11e3-b3b2-e716f9080d50
#FIXED_RANGE=172.31.1.0/24
#FLOATING_RANGE=192.168.20.0/25
#HOST_IP=10.3.4.5
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-meta
RECLONE=yes
2. pip install tempest
3. ls /etc/tempest -> shows nothing
4. tempest init cloud-01
