> -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.-
