[jira] [Created] (HIVE-20251) Improve message in SharedWorkOptimizer when cycles are found in the plan

Jesus Camacho Rodriguez created HIVE-20251:
----------------------------------------------

             Summary: Improve message in SharedWorkOptimizer when cycles are found in the plan
                 Key: HIVE-20251
                 URL: https://issues.apache.org/jira/browse/HIVE-20251
             Project: Hive
          Issue Type: Improvement
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


Currently, if there is a cycle, e.g., due to semijoin, which should not happen, SharedWorkOptimizer will just loop infinitely. It would be better to throw an Exception in those cases.
