Jonathan Gray commented on HBASE-3268:
--------------------------------------
I think rather than needing to do much more frequent load balances or just in
addition to them, we should add more intelligence into non-balancing region
assignment (all random now). And we could also lazily move splits off their
original server.
But for now making it more aggressive at one minute or so should be fine.
> Auto-tune balance frequency based on cluster size

> Right now we only balance the cluster once every 5 minutes by default. This
> is likely to confuse new users. When you start a new region server, you
> expect it to pick up some load very quickly, but right now you have to wait 5
> minutes for it to start doing anything in the worst case.
> We could/should also add a button/shell command to "trigger balance now"
