Zhihong Yu commented on HBASE-5231:
-----------------------------------
bq. I do not know what that means (it seems out of scope for this patch)
The relationship between this feature and balancer sloppiness is definitely
within the scope of discussion.
This is about how we judge whether a cluster is balanced (even without this
backport). Since the existing tests for load balancer pass, there is no
regression introduced by this feature.
bq. Isn't this a balancer implementation detail? It would figure how to ask
this?
Currently only HRegionInfo is passed to balancer which is static information.
Meaning, balancer lacks statistics about the load on each region.
bq. If it can't, then we need to beef up the balancer interface api so this
stuff is passed in.
Sure. This is to be solved in another JIRA.
