Viraj Jasani commented on HBASE-24459:
--------------------------------------
Thanks [~zhangduo].
{quote}at server side, we will provide caches at backup masters to handle the
requests.
{quote}
This means backup masters will have to talk to active HMaster(through client /
ZKConnectionRegistry?) to get latest RegionLocations for meta since we can't
get that detail from ZK anymore?
