             Summary: Vectorization: Disable exotic field reference form
                 Key: HIVE-19035
                 URL: https://issues.apache.org/jira/browse/HIVE-19035
             Project: Hive
          Issue Type: Bug
          Components: Hive
    Affects Versions: 3.0.0
            Reporter: Matt McCline
            Assignee: Matt McCline


We currently don't support exotic field references like get a struct field from 
array<struct<a:timestamp>> returns a type array<timestamp>.  Attempt causes 
ClassCastException in VectorizationContext that kills query planning.

The Q file is input_testxpath3.q
