Francis Liu commented on HBASE-11165:
-------------------------------------
We're currently using huge NNs.
We haven't looked into the number of inodes as that didn't seem to be an issue
for the 1M case (We have a single NN running ~250M files). But we'll be
watching it for the post 1M benchmarks. Will post results here.
> 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.
