Enis Soztutar commented on HBASE-11006:
---------------------------------------
Thanks Gregory. This also applied to some other table names as well like lib,
etc. The problem is in the HConstants.HBASE_NON_TABLE_DIRS.
This is easily reproducible, and instead of throwing an exception and not
allowing the table creation, or this working as expected, the bug results in
the region not being able to open.
> Cannot create 'data' table
> --------------------------
>
> Key: HBASE-11006
> URL: https://issues.apache.org/jira/browse/HBASE-11006
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.96.0
> Reporter: Gregory Hart
>
> 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:
