             Summary: DrillOptiq should raise appropriate error message while dealing with unknown RexNode
                 Key: DRILL-3305
                 URL: https://issues.apache.org/jira/browse/DRILL-3305
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Mehant Baid


Currently for certain types of RexNodes (RexOver, RexCorrelVariable) DrillOptiq does not convert it to the equivalent logical expressions. In that case we simply return a NullExpression (minor type: Null) and we error out later in execution when we try to allocate a vector with minor type Null. We should error out early in DrillOptiq that there was a planning issue indicating the particular RexNode that wasn't handled correctly.
