Enis Soztutar commented on HBASE-8344:
--------------------------------------
Please don't use this construct (not that readable):
{code}
if ((serverWithLegitStartCode = availableServersContains(servers, s)) != null) {
{code}
segregateRegions() does not only seperate the regions with favorite nodes, but
also assigns them. Should we rename it?
it seems the roundrobin assignment is not randomized, so if if 100 nodes, I
create 3 tables all with 30 regions, they all go to the same 30 racks and RSs.
We might reuse bits of DefaultLB#roundRobinAssignment(). Other strategies might
be to look into loads / or keep the state from last round robin assignment, but
simple randon should be fine as a first cut.
> Improve the assignment when node failures happen to choose the secondary RS
> as the new primary RS
