----------------------------------------------
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.
