stack commented on HBASE-11165:
-------------------------------
bq. Francis Liu HBASE-11241 was opened to support multiple active masters with
replicated state (vs. current active-backups) for better HA, and you are
referring to partitioned master, right?
Scaling, the thought is that we need more masters to spread the work
(partitioning). We also need the HA if we don't want to have state straddle
processes (master and zk (and hdfs)).
> 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.
