Lars Hofhansl commented on HBASE-11165:
---------------------------------------
bq. Do we need to bring root back? Can't we simply host all of root in
zookeeper?
Came here to say exactly that. Enis beat me to it. Can we please not bring back
root? We need a bootstrapping mechanism to find root anyway, and if we can do
that we should be able to bootstrap a few dozen meta regions from there.
Currently we'd use ZK for that, but we don't have to.
> Scaling so cluster can host 1M regions and beyond (50M regions?)

> This discussion issue comes out of "Co-locate Meta And Master HBASE-10569"
> and comments on the doc posted there.
> A user -- our Francis Liu -- needs to be able to scale a cluster to do 1M
> regions maybe even 50M later. This issue is about discussing how we will do
> that (or if not 50M on a cluster, how otherwise we can attain same end).
> More detail to follow.
