> In branch-1 and master we have some improvement and new features on scanning which is
not compatible.
> A client of old version to a server of new version is compatible (must be a bug if not,
maybe need some test?). 
> A client of new version may not be able to read from a server of old version correctly
(because of scan limit, moreResults flag, etc), which is ok for major/minor upgrade and we
can tell users to upgrade server before upgrading client. But RS also use scan to read meta.
If meta table is in RS of old version, all RSs of new version may have trouble while scanning
meta table.
> So we should make sure meta table always in servers of new version. Force meta table
in Master and upgrade Master first, or assign meta table in region servers with latest version?
