Iceberg have to, is it turned on automatically or do I have to set up things

Question 1: OCC is only for `CommitFailedException` with 4 retries, but fail
immediately for other cases.
Question 2: Maybe `base_table` is in `COPY_ON_WRITE` mode? Please try to
change the table property to `MERGE_ON_READ`.
```java
public static final String MERGE_MODE = "write.merge.mode";
// public enum RowLevelOperationMode {
// COPY_ON_WRITE("copy-on-write"),
// MERGE_ON_READ("merge-on-read");
// }
public static final String MERGE_MODE_DEFAULT =
RowLevelOperationMode.COPY_ON_WRITE.modeName();
```
