On app-dev master, I try to fix etcdctl.

update:

The dependency of etcd, dnspython end its support for python2 after 1.16.0. But when install the package, it will install the newest version. So it would be incompatible.

After install dnspython 1.16.0, it start normally.

We need to move etcdstat to python3, or specify the version of package in setup.py.

@theggs How did you upgraded it? You have to use latest tw-ansible-role for it. Did you re-run ansible playbook?

[theggs]

No, I reinstall the packages.

[centos@dev-work01 ~]$ sudo pip install dnspython==1.16.0 tw-etcdstat==0.1.1.post25

Should I rerun tw-ansible-role for it?

[theggs]

The roles are mantains by support team. I need to ask them to do that.

[Holm78]

@theggs yes, etcdstat should be updated using by running ansible role from latest tw-ansible-roles repository.
