             Summary: Needs to capture input/output entities in explainRewrite
                 Key: HIVE-23461
                 URL: https://issues.apache.org/jira/browse/HIVE-23461
             Project: Hive
          Issue Type: Improvement
            Reporter: Wenchao Li


HIVE-18778(CVE-2018-1314) capture input/output entitles in explain semantic analyzer so when a query is disallowed by Ranger, Sentry or Sqlstd authorizizer, the corresponding explain statement will be disallowed either.

However, ExplainSQRewriteSemanticAnalyzer also uses an instance of DDLSemanticAnalyzer to analyze the explain rewrite query.

 
{code:java}
SemanticAnalyzer sem = (SemanticAnalyzer)
 SemanticAnalyzerFactory.get(queryState, input);
sem.analyze(input, ctx);
sem.validate();

The inputs/outputs entities for this query are never set on the instance of ExplainSQRewriteSemanticAnalyzer itself and thus is not propagated into the HookContext in the calling Driver code. It is a similar issue to HIVE-18778.{code}
