             Summary: CalcitePlanner.genOpTree tries to run with cbo disable even after a semantic analysis exception
                 Key: HIVE-12580
                 URL: https://issues.apache.org/jira/browse/HIVE-12580
             Project: Hive
          Issue Type: Bug
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan


The following code in CalcitePlanner.genOPTree looks buggy : 

{code}
          if (!conf.getBoolVar(ConfVars.HIVE_IN_TEST) || isMissingStats
              || e instanceof CalciteSemanticException) {
            reAnalyzeAST = true;
          } else if (e instanceof SemanticException) {
            throw (SemanticException) e;
          } else if (e instanceof RuntimeException) {
            throw (RuntimeException) e;
          } else {
            throw new SemanticException(e);
          }
{code}

If we have missing stats and a Semantic exception thrown from from the try block, we still go ahead and continue to generate a plan with cbo turned off.
