Mikhail Antonov commented on HBASE-11059:
-----------------------------------------
To recap some of the notes from the doc, to discuss further..
- the "atomic" short-circuit updates of META are only possible if META is
guaranteed to be hosted on active master, which is not the case if HBASE-10569
topology is turned off, unless I'm missing something?
- if we had system table with statistics (like region size, number of rows in
each one etc) we could do master-initiated splits and merges - do you think it
would be beneficial in terms of more even load on Master [~jxiang]?

> It seems that most people don't like region assignment with ZK (HBASE-5487),
> which causes many uncertainties. This jira is to support ZK-less region
> assignment. We need to make sure this patch doesn't break backward
> compatibility/rolling upgrade.
