RocFang opened a new pull request #2390:
URL: https://github.com/apache/apisix/pull/2390
### What this PR does / why we need it:
1. the result below will always be false ,since etcd_version is nil:
```lua
if (etcd_version == "v3" and not res:find("OK", 1, true)) then
is_success = false
if (index == host_count) then
error(cmd .. "\n" .. res)
end
break
end
```
and since etcd_version has been checked before, I think maybe there is no
need to check it again here.
2. cluster_version has been defined previously, no need to define a new
local one.
