Project: Flink
Issue Type: Bug
Components: State Backends, Checkpointing
Affects Versions: 1.5.0
Reporter: Sihua Zhou

In full checkpoint, `kvStateInformation` is not a copied object and it can be
changed when writeKVStateMetaData() is invoking ... This can lead to
problematic, which is serious.
{code}
private void writeKVStateMetaData() throws IOException {
// ...
for (Map.Entry<String, Tuple2<ColumnFamilyHandle,
RegisteredKeyedBackendStateMetaInfo<?, ?>>> column :
stateBackend.kvStateInformation.entrySet()) {
}
//...
}
{code}
