             Summary: Bridge cases in which Calcite's type resolution is more 
stricter than Hive.
                 Key: HIVE-20940
                 URL: https://issues.apache.org/jira/browse/HIVE-20940
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltan Haindrich
            Assignee: Zoltan Haindrich


Calcite is more stricter w.r.t common types than Hive.

For example in case a CASE with different types on the branches is not 
something Calcite likes:
{code}
CASE
  WHEN cond1 THEN booleanCol
  WHEN cond2 THEN stringCol
  WHEN cond3 THEN floatCol
  ELSE doubleCol
END
{code}
