Jimmy Xiang commented on HBASE-12453:
-------------------------------------
We used to update znode, then update meta. In this case, it is something like
"update znode" vs "notify master". This should not be an issue.
The issue is that if master is down, we can't notify master now. That's what I
was thinking about.
> Make region available once it's open

> Currently (in trunk, with zk-less assignment), a region is available to
> serving requests only after RS notifies the master the region is open, and
> the meta is updated with the new location. We may be able to do better than
> this.
