> Key: FLINK-5300
> URL: https://issues.apache.org/jira/browse/FLINK-5300
> Project: Flink
> Issue Type: Improvement
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0, 1.1.3
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Critical
>
> Flink's behaviour to delete {{FileStateHandles}} and closing
> {{FsCheckpointStateOutputStream}} always triggers a delete operation on the
> parent directory. Often this call will fail because the directory still
> contains some other files.
> A user reported that the SRE of their Hadoop cluster noticed this behaviour
> in the logs. It might be more system friendly if we first checked whether the
> directory is empty or not. This would prevent many error message to appear in
> the Hadoop logs.
