Zach York commented on HBASE-18478:
-----------------------------------

[~stack] These are the only uses in the codebase besides the other 
loadbalancers using regionFinder to create the cluster which is the point of 
this patch, so we are good. 

It doesn't look like any of the unit test failures are related (most of them 
are timeouts and this is a configured setting so it should have no default 
change).

> Allow users to remove RegionFinder from LoadBalancer calculations if no 
> locality possible

> BaseLoadBalancer should have the option to remove RegionFinder from load 
> balancing. This provides significant cluster start time reduction for 
> FileSystems that do not surface locality such as Amazon S3.
