Example 1 with GenericAppenderFactory

use of org.apache.iceberg.data.GenericAppenderFactory in project hive by apache.

the class HiveIcebergTestUtils method createEqualityDeleteFile.

 * @param rowsToDelete The rows that should be deleted. It's enough to fill out the fields that are relevant for the
 *                     equality check, as listed in equalityFields, the rest of the fields are ignored
 * @return The DeleteFile created
 * @throws IOException If there is an error during DeleteFile write
