> As discussed in HIVE-25420 time column is not native Hive type, reading it is more complicated, and is not supported for vectorized read. Trying this currently results in an exception for ORC formatted files, so we should make an effort to gracefully fall back to non-vectorized reads when there's such a column in the query's projection.
