> Before we have the state-of-art Procedure V2 feature (HBASE 1.0 release or

> The above call trace is from a 0.98.x test run. We saw similar issue in
> 1.0.x run, too.
> The proposed fix is to ignore the zk node and force namespace table creation
> to be complete so that master can start successfully.
