   @pvary Thanks for your reply.  I agree that creating an extra record is not a good way to solve vectorization problem in hive, we need to find another way to solve this problem.
   
   [TEZ-4248](https://issues.apache.org/jira/browse/TEZ-4248) is a better way to solve  projection issue on tez.  BTW, do we need to change [this assert](https://github.com/apache/iceberg/blob/19622dcfcb426485748fa017a6181e23df5732dc/mr/src/main/java/org/apache/iceberg/mr/hive/HiveIcebergSerDe.java#L112-L118) currently since this issue happens no matter whether `hive.vectorized.execution.enabled` is enabled ?
