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