Thanks Ted and Stack.  I did not observe the failure as i had left the office by that time..

Regarding the config update in hbase-default.xml i was not very clear if it was needed.  Thanks
Stack for taking care of it. :)

>          Issue Type: Task
>    Affects Versions: 0.92.0
>            Reporter: Jean-Daniel Cryans
>            Assignee: ramkrishna.s.vasudevan
>            Priority: Blocker

>         Attachments: 4815-v2.txt, 4815.addendum, 4815.patch
> 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).
