> -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.-
