URL: https://github.com/apache/iceberg/issues/7586
### Apache Iceberg version
1.2.1 (latest release)
### Query engine
Spark
### Please describe the bug 🐞
When executing the following test case, which aims to rewrite files with
ZORDER, Spark throws an error:
```
@Test
public void testZOrderSortPartitionEvolution() {
int originalFiles = 20;
Table table = createTable(originalFiles);
shouldHaveLastCommitUnsorted(table, "c2");
shouldHaveFiles(table, originalFiles);
Stream.of(Expressions.bucket("c1", 2), Expressions.bucket("c2", 4))
.forEach(expr -> table.updateSpec().addField(expr).commit());
long dataSizeBefore = testDataSize(table);
RewriteDataFiles.Result result =
basicRewrite(table)
.zOrder("c2", "c3")
.option(
SortStrategy.MAX_FILE_SIZE_BYTES,
Integer.toString((averageFileSize(table) / 2) +
2))
// Divide files in 2
.option(
RewriteDataFiles.TARGET_FILE_SIZE_BYTES,
Integer.toString(averageFileSize(table) / 2))
.option(SortStrategy.MIN_INPUT_FILES, "1")
.execute();
Assert.assertEquals("Should have 1 fileGroups", 1,
result.rewriteResults().size());
assertThat(result.rewrittenBytesCount()).isEqualTo(dataSizeBefore);
}
```
The error is as follows:
```
Cannot find field 'ICEZVALUE' in struct: struct<1: c1: optional int, 2: c2:
optional string, 3: c3: optional string>
