Huaxiang Sun commented on HBASE-18070:
--------------------------------------
{quote}I agree with most of your answers. The only thing is that I do not think
the current solution can not provide HA, if the ‘HA’ here is something similar
to the old read replicas feature. Client has built in retries so if we fail to
request a replica then we will go to another one, unless all the replicas are
down. But if all the replicas are down, the old read replicas feature can not
solve the problem either.

I agree with you here. It is doable, but this is not implemented in the current
code. We need to add a follow-up Jira to support it.
