The fix is to use the RS's timestamp for the > server column in meta update, but that actually opens up a vulnerability for > clock skew (see the discussions in the jira). > For the region replicas case, we can reproduce a problem where the server > name field is eclipsed by the masters earlier update because the RS is > lagging behind. However, this is not specific to replicas, but occurs more > frequently with it. > One option that was discussed was to send the master's ts with open region > RPC and use it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
