> Now what we get from HiveSemanticAnalyzerHookContextImpl is limited. If we have hook of HiveSemanticAnalyzerHook, we may want to get more things from hookContext. (e.g. the needed colums from query).
> So we should get instance of HiveSemanticAnalyzerHookContext from configuration, extends HiveSemanticAnalyzerHookContext with a new implementation, overide the HiveSemanticAnalyzerHookContext.update() and put what you want to the class.
