Subject Re: HBase Load Balancer
Date Thu, 28 Sep 2017 23:04:57 GMT
StochasticLoadBalancer takes care of both request counts and number of
regions.

hbase.master.balancer.stochastic.regionCountCost controls the weight for
region count, default to 500.

hbase.master.balancer.stochastic.readRequestCost controls read request
weight, default to 5.

hbase.master.balancer.stochastic.writeRequestCost controls write request
weight, default to 5.

For second part of question, see
http://hbase.apache.org/book.html#arch.regions.size
