> Key: FLINK-10346
> URL: https://issues.apache.org/jira/browse/FLINK-10346
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Affects Versions: 1.5.3, 1.6.0, 1.7.0
> Reporter: Till Rohrmann
> Priority: Major
> Labels: stale-major
>
> The {{StateBackendLoader}} creates a random subdirectory under
> {{HighAvailabilityOptions.HA_STORAGE_PATH}} for the {{MemoryStateBackend}} if
> no checkpointing directory has been specified (see
> {{StateBackendLoader.java:246}}). The problem is that this directory gets
> never removed after the {{MemoryStateBackend}} is closed. It is important to
> clean up these created directories.
