Is this bug caused by "yum swap" command?   Will there be same issue if we migrate Etcd in future?  For example: migrate etcd-2.x to etcd-3.0.15-x; migrate etcd3-3.0.14.x to etcd-3.0.15-x.

Comment 4 Jan Chaloupka 2016-12-12 11:41:19 UTC
Hi Anping,

etcd3 is going to be obsoleted by etcd-3.0.15 in 7.3.2. Once done, no need to yum swap.
