             Summary: When an IterOutcome is NONE, do not access the batch
                 Key: DRILL-254
                 URL: https://issues.apache.org/jira/browse/DRILL-254
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Ben Becker
            Assignee: Jacques Nadeau


Data associated with a RecordBatch/RootExec in the NONE state should not be 
relied upon.

This requires changes to logic in various parts of the code base; if an 
operator returns a NONE state, do not attempt to access the batch (e.g. record 
count, field metadata, value vectors, etc.).
