-------------------------------------

             Summary: ExplainSemanticAnalyzer shares QueryState between statements
                 Key: HIVE-16442
                 URL: https://issues.apache.org/jira/browse/HIVE-16442
             Project: Hive
          Issue Type: Bug
            Reporter: Eugene Koifman


explain analyze .....
will call the Driver recursively to actually execute the query
when it does
{noformat}
BaseSemanticAnalyzer sem = SemanticAnalyzerFactory.get(queryState, input);
{noformat}

it ends up sharing QueryState between different query executions
