> 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.
