Huaxiang Sun commented on HBASE-18070:
--------------------------------------
Hi [~anoop.hbase], the logic is somehow already there? Let's client goes to rs1
for regionA, if regionA does not exist at rs1, an Exception will be sent back
and client will query meta again. If replication is enabled for meta, it can be
leveraged for meta load balancing. Let's say there are meta-primary,
meta-replica1, meta-replica2. Client goes to meta-replica1 for location, assume
that there is stale data, then client will query meta again (it can go to
meta-replica1 again, hope it catches up already, or after a few try, it can go
to meta-primary).
