Description

https://github.com/apache/hbase/pull/2643

 

With my operator hat on, I'd assume that LOAD_BALANCE with 1 replica count works like no read replicas configured (logic wise at-least, even though the code paths are different).

If the server side does not support meta replica, the client side cannot be configured to support this mode

Since clients are usually long running (meaning we may not be able to restart client or they using cached HBase connection) and meta replica count can be altered on the service side on the fly, I'd expect client to work across these changes without any configuration changes. WDYT?
