Mikhail Antonov commented on HBASE-11059:
-----------------------------------------
[~jxiang] looks like other jiras like HBASE-7767 would benefit from notion of
extended system (meta) tables? Also, if region assignment is ZK-less,
HBASE-10909 would benefit too :)
bq. without storing transient states in ZK
Table state isn't transient state, is it?
Would client need to access this table to find out about assignment/state?
> ZK-less region assignment

> 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.
