> Key: FLINK-8777
> URL: https://issues.apache.org/jira/browse/FLINK-8777
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.5.0
> Reporter: Sihua Zhou
> Assignee: Sihua Zhou
> Priority: Major
> Fix For: 1.5.0
>
>
> When recovery from failed, {{TaskLocalStateStoreImpl.retrieveLocalState()}}
> will be invoked, we can release all entry from
> {{storedTaskStateByCheckpointID}} that does not satisfy {{entry.checkpointID
> == checkpointID}}, this can prevent the resource leak when job loop in
> {{local checkpoint completed => failed => local checkpoint completed =>
> failed ...}}.
