Ted Yu commented on HBASE-3609:
-------------------------------
Empty server can be detected within balanceCluster(). But this detection has
been performed by Master, hence the flag.
The static regionId helps make each region Id unique. I actually utilized this
fact to debug my code.
Let me think more about writing unit test(s) that verifies the distribution
over underloaded servers.
Both TestLoadBalancer and TestAdmin pass.
Preliminary response from Stan Barton showed improvement over random selector.
I am waiting for further feedback from gaojinc...@huawei.com and Stan.
