Ted Yu commented on HBASE-11006:

Here is the stack trace, from the above mentioned forum:
I see this error message on the region server:

>                 URL: https://issues.apache.org/jira/browse/HBASE-11006
>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.96.0
>            Reporter: Gregory Hart
>            Assignee: Gustavo Anatoly
>              Labels: noob
>             Fix For: 0.99.0
>         Attachments: HBASE-11006.patch
> Starting with HBase 0.96, it is not possible to create a table named 'data'. When a user
tries to create a table named 'data', the table is added to the metastore but the region server
fails to open the region.
> To reproduce, I just run “hbase shell” and type in:
> create ‘data’, ‘cf’
> This was also verified on Apache HBase trunk by Enis from the Hortornworks forums. His
comment on the bug:
> There has been a change in the directory layout in HBase 0.96 for introducing namespaces.
The HBase root directory now keeps all table data under the sub-directory “data”. I suspect
the error is somewhere there.
> More info can be found on the thread in the Hortornworks forums:
