I tested the master code in Spark 3.4.0 and it works correctly.
```scala
scala> spark.sql("create table local.db.test_short(id short) using
iceberg").show()
++
||
++
++
scala> spark.sql("insert into local.db.test_short values(1), (2),
(3)").show()
++
||
++
++
scala> spark.sql("select * from local.db.test_short").show()
+---+
| id|
+---+
| 1|
| 2|
| 3|
+---+
scala> spark.sql("select * from local.db.test_short where id = 2").show()
+---+
| id|
+---+
| 2|
+---+
```
It seems Iceberg promotes the short to int:
```scala
scala> spark.sql("desc table local.db.test_short").show()
+--------+---------+-------+
|col_name|data_type|comment|
+--------+---------+-------+
| id| int| null|
+--------+---------+-------+
```
