> This patch introduces CBO step in SemanticAnalyzer. For now the
> CostBasedOptimizer is an empty shell.
> The contract between SemAly and CBO is:
> - CBO step is controlled by the 'hive.enable.cbo.flag'.
> - When true Hive SemAly will hand CBO a Hive Operator tree (with operators
> annotated with stats). If it can CBO will return a better plan in Hive AST
> form.
