> Disable online altering by default, create a config for it

> Key: HBASE-4815
> URL: https://issues.apache.org/jira/browse/HBASE-4815
> Project: HBase
> Issue Type: Task
> Affects Versions: 0.92.0
> Reporter: Jean-Daniel Cryans
> Assignee: ramkrishna.s.vasudevan
> Priority: Blocker
> Fix For: 0.92.0

> There's a whole class of bugs that we've been revealing from trying out
> online altering in conjunction with other operations like splitting.
> HBASE-4729, HBASE-4794, and HBASE-4814 are examples.
> It's not so much that the online altering code is buggy, but that it wasn't
> tested in an environment that permits splitting.
> I think we should mark online altering as experimental in 0.92 and add a
> config to enable it (so it would be disabled by default, requiring people to
> enable for altering table schema).
