Ted Yu commented on HBASE-4191:
-------------------------------
Currently assignAllUserRegions() reads "hbase.master.startup.retainassign" and
if the value is true, balancer.retainAssignment() is called.
Looks like new config parameter should be introduce, e.g.
"hbase.master.startup.policy", to accommodate the above and future enhancements.
> Utilize getTopBlockLocations in load balancer

> the region server with the highest block affinity.
