Ted Yu created FLINK-6467:
-----------------------------
Summary: Potential lack of synchronization w.r.t. newSstFiles in
RocksDBKeyedStateBackend#releaseResources()
Key: FLINK-6467
URL: https://issues.apache.org/jira/browse/FLINK-6467
Project: Flink
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
{code}
if (canceled) {
List<StateObject> statesToDiscard = new ArrayList<>();
statesToDiscard.add(metaStateHandle);
statesToDiscard.addAll(miscFiles.values());
statesToDiscard.addAll(newSstFiles.values());
{code}
It seems access to newSstFiles should be protected by
stateBackend.asyncSnapshotLock
