stack updated HBASE-5959:
-------------------------
Release Note:
Added a new StochasticLoadBalancer that when enabled will perform a randomized
search for the optimal cluster balance. The new balancer takes into account
data locality, storefile size, memstore size, and the evenness of tables over
region servers when trying potential new cluster states.
To enable the new balancer set hbase.master.loadbalancer.class to
org.apache.hadoop.hbase.master.balancer.StochasticLoadBalancer . It is also
recommended to set hbase.master.loadbalance.bytable to false . Lots of
different configuration options can be tuned to prioritize costs differently.
Explanations of all of the configuration options are available on the JavaDoc
for StochasticLoadBalancer.
StochasticLoadBalancer is the default in 0.96.0
