Hi ceilometer team and all,
After a patch[1] was merged, Tacker zuul check fails because ceilometer
devstack installation error[2]. Do you have any work aroud of this
problem?

Addition, why devstack uses pip version 9.0.3 when installing python
packages? The cause of our problem is installation error of
conluent-kafka. But with latest pip (version 19), I was able to install
the package.
