Andrew Purtell commented on HBASE-11780:
----------------------------------------
Do you envision this as an improved cost function for the
StochasticLoadBalancer?
How will heterogeneous hardware node attributes be discovered and communicated
to the balancer?
Is static node weighting in clusters of ~hundreds or ~thousands viable? Assume
some hardware is always in churn. How would updates be communicated to the
master? If by flat file somewhere, will we have to restart the master for
changes to take effect?
Elsewhere it has been discussed that we'd like to slim down and ultimately
remove RegionLoad and replace that duplication of our metrics publishing with a
metrics listener on the master that accomplishes the same end. Would this issue
work towards or against that goal?

> In some situations with heterogeneous hardware it might be helpful to take in
> account the available resources such as RAM, cores or spindles before for the
> region assignment. A form of weight per RS might be an initial approach but
> for also a limit of open regions in a RS or maximum open store files could be
> used.
