Thiruvel Thirumoolan commented on HBASE-15531:

As part of these enhancements, we are planning to remove the following classes since no-one
is using favored nodes.

1. FavoredNodeLoadBalancer. FavoredNodeLoadBalancer will be replaced by FavoredStochasticLoadBalancer
with additional pickers and a RSGroup based equivalent.

2. RegionPlacementMaintainer (RPM) - This is currently large, will replace this with smaller
