             Summary: Add support for reading Iceberg's time columns with 
vectorization turned on
                 Key: HIVE-25421
                 URL: https://issues.apache.org/jira/browse/HIVE-25421
             Project: Hive
          Issue Type: Bug
            Reporter: Ádám Szita
            Assignee: Ádám Szita


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, so we should make an effort to
 * either gracefully fall back to non-vectorized reads when there's such a 
column in the query's projection
 * or work around the reading issue on the execution side.
