Michael Stack commented on HBASE-24152:
---------------------------------------
Was reviewing the PR but figured don't have enough understanding of what is
going on so let me ask here.
I don't follow why the PR is special casing SSD weight. Why it it not just
factored into the host general weight? Balancer works at the RS level, not at
type of storage? A local replica should be favored whether on ssd or not?
Help me out [~filtertip] Thank you.
