stack commented on HBASE-12007:
-------------------------------
bq. We could assign to backup master?
But it is off by default in branch-1?
bq. Very hard, and it is useful for most of use cases.
But it is off in branch-1 (smile). I think it fine that M can be a RS but that
it is not on by default.
bq. Regions on master are handled with balanceMasterRegions which is internal
to the balancer.
... ok, so only one way of distributing regions... the balancer?
Thanks for bringing me along [~jxiang]

> We should enhance how StochasticBalancer picks up a random server so that it
> can avoid putting user regions on master, because regions on master are
> handled differently in a separate method.
