------------------------------------
Summary: Get instance of HiveSemanticAnalyzerHookContext from
configuration
Key: HIVE-7730
URL: https://issues.apache.org/jira/browse/HIVE-7730
Project: Hive
Issue Type: Bug
Reporter: Xiaomeng Huang
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.
