> If CreateTableProcedure rolls back, depending on the steps of the procedure, it might
not change the table state to be 'Deleted' or just delete the table state.  
> In branch-1 and its child branches, the following exception will throw if the table is
created again and the previous rollback is not clean:
> {noformat}
> 2015-05-30 06:30:05,287 WARN [ProcedureExecutorThread-1] procedure.CreateTableProcedure:
The table xyz does not exist in meta but has a znode. run hbck to fix inconsistencies.
> {noformat}
> In master branch, the table state is not checked during CreateTableProcedure#prepareCreate(),
but we still need to make sure that the table state is in a consistent state.
