I know there were some changes in .90 in terms of how region balancing occurs. Is there a resource somewhere that describes the options for the configuration? Per Jonathan Gray's recommendation we are trying to keep our region count down to 100 per region server (we are up to 5gb region size). This has caused us to get a lot of hot spots relative to what we saw with 1000 regions per node. Scanning through #3373 it sounded like there is a round-robin load balancer we can turn on instead of keeping regions pinned as I believe they are in .90 by default. We have many tables and certain region servers seem to get "stuck" with a single table's data in almost contiguous ranges which really throws a wrench in our load balancing.
Thanks.
