Bowen Li updated FLINK-8411:
----------------------------
Priority: Critical (was: Major)
> inconsistent behavior between HeapListState#add() and RocksDBListState#add()
> ----------------------------------------------------------------------------
>
> Key: FLINK-8411
> URL: https://issues.apache.org/jira/browse/FLINK-8411
> Project: Flink
> Issue Type: Bug
> Affects Versions: 1.4.0
> Reporter: Bowen Li
> Assignee: Bowen Li
> Priority: Critical
> Fix For: 1.5.0, 1.4.1
>
>
> You can see that HeapListState#add(null) will result in the whole state being
> cleared or wiped out.
> {code:java}
> // HeapListState
> @Override
> public void add(V value) {
> final N namespace = currentNamespace;
> if (value == null) {
> clear();
> return;
> }
> final StateTable<K, N, ArrayList<V>> map = stateTable;
> ArrayList<V> list = map.get(namespace);
> if (list == null) {
> list = new ArrayList<>();
> map.put(namespace, list);
> }
> list.add(value);
> }
> {code}
> {code:java}
> // RocksDBListState
> @Override
> public void add(V value) throws IOException {
> try {
> writeCurrentKeyWithGroupAndNamespace();
> byte[] key = keySerializationStream.toByteArray();
> keySerializationStream.reset();
> DataOutputViewStreamWrapper out = new
> DataOutputViewStreamWrapper(keySerializationStream);
> valueSerializer.serialize(value, out);
> backend.db.merge(columnFamily, writeOptions, key,
> keySerializationStream.toByteArray());
> } catch (Exception e) {
> throw new RuntimeException("Error while adding data to
> RocksDB", e);
> }
> }
> {code}
