mohsenify opened a new issue, #12652:
URL: https://github.com/apache/iceberg/issues/12652
### Apache Iceberg version
1.7.1
### Query engine
None
### Please describe the bug 🐞
When writing data using Iceberg on local Minio with the Hadoop catalog,
everything works fine. However, when switching to Nessie catalog or REST
catalog, an exception occurs after the first write operation.
Steps to Reproduce
- Write data using Iceberg with the Hadoop catalog (works fine).
- Switch to Nessie or REST catalog.
- Perform the first write (succeeds).
- Attempt a second write (fails with an exception).
My code:
` public void insert(List<Record> records, String tableName) {
String fileName = UUID.randomUUID().toString();
Table table = getTable(tableName);
Map<String, List<Record>> partitionedRecords =
records.stream().collect(Collectors.groupingBy(rec ->
Objects.equals(table.spec(), PartitionSpec.unpartitioned()) ?
table.locationProvider().newDataLocation(fileName) :
table.locationProvider().newDataLocation(table.spec(), rec,
fileName))
);
List<DataFile> dataFiles =
partitionedRecords.entrySet().stream()
.map(e -> writeRecordsToFile(e.getKey(), e.getValue(),
table)).toList();
addFilesToTable(dataFiles, table);
}
private void addFilesToTable(List<DataFile> dataFiles, Table table) {
AppendFiles appendFiles = table.newAppend();
dataFiles.forEach(appendFiles::appendFile);
appendFiles.commit();
}`
Exception:
`java.lang.IllegalStateException: Cannot create data file from unclosed
writer`
