Review Comment:
I was able to reproduce the issue locally with breakpoints.
I put a breakpoint to `IcebergStreamWriter.open` method:
https://github.com/apache/iceberg/blob/fbcd142c5dc1ec99792ef8edc1378e3a027fecf7/flink/v1.19/flink/src/main/java/org/apache/iceberg/flink/sink/IcebergStreamWriter.java#L53
I started the test, and only allowed to continue one of the writer threads,
and kept the other blocked.
After a while I have seen that the job is cancelled:
```
switched from CANCELING to CANCELED.
```
At this point I have released the other breakpoint as well, and as a result,
I have got the same exception as in
https://github.com/apache/iceberg/issues/10356
Not sure about the fix yet...
I got a different exception when I put a breakpoint to
[here](https://github.com/apache/iceberg/blob/b7d3a7f9d33aae2a85f9a742ed1ab87608283d28/flink/v1.19/flink/src/test/java/org/apache/iceberg/flink/source/TestIcebergSourceFailover.java#L141)
