---------------------------------------------

             Summary: Indexing non-arrays yields AssertionError
                 Key: DRILL-3135
                 URL: https://issues.apache.org/jira/browse/DRILL-3135
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Daniel Barclay (Drill)


Trying to index into a non-array yields an AssertionError (with no error message other than a type name) rather that a message referring to the problem (e.g., that an array indexing operation was applied to an expression whose type turned out to be a non-array type):
