Subject [jira] [Created] (CALCITE-1653) Allow for custom RelOptPlanner.Executor in RexUtil.simplify
Date Wed, 22 Feb 2017 15:04:44 GMT
Remus Rusanu created CALCITE-1653:
-------------------------------------

             Summary: Allow for custom RelOptPlanner.Executor in RexUtil.simplify
                 Key: CALCITE-1653
                 URL: https://issues.apache.org/jira/browse/CALCITE-1653
             Project: Calcite
          Issue Type: Bug
            Reporter: Remus Rusanu
            Assignee: Julian Hyde


{{RexUtil.simplify}} (and derivatives) use a default {{EXECUTOR}} for evaluating literals
and expression in {{simplifyCast}}. This causes value differences from Hive, triggering issues
like CALCITE-1650, CALCITE-1651.
