PengFei Li updated FLINK-13469:
-------------------------------
Description:
Currently, resource used by `StateMapSnapshot` is released in
`AbstractStateTableSnapshot#writeStateInKeyGroup` as follows
{code:java}
public void writeStateInKeyGroup(@Nonnull DataOutputView dov, int keyGroupId)
throws IOException
{ StateMapSnapshot<K, N, S, ? extends StateMap<K, N, S>> stateMapSnapshot =
getStateMapSnapshotForKeyGroup(keyGroupId);
stateMapSnapshot.writeState(localKeySerializer, localNamespaceSerializer,
localStateSerializer, dov, stateSnapshotTransformer);
stateMapSnapshot.release(); }
{code}
If exception happens in `StateMapSnapshot#writeState`, resources used by this
`StateMapSnapshot` and the left can not be released.
