Jimmy Xiang commented on HBASE-11165:
-------------------------------------

It may take a while for a single master to assign 50 million regions. It is also quite some load to the ZK if we use ZK for region assignment.

> 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.
