> Before we have the state-of-art Procedure V2 feature (HBASE 1.0 release or older), we
frequently see the following issue (orphaned ZK node) that prevent master to start (at least
in testing):

> 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.
