> The {{RocksDBStateBackend}} extracts the RocksDB jni library from the RocksDB dependency
in a temp directory (see {{RocksDBStateBackend#ensureRocksDBIsLoaded}}). This file is, however,
never removed. 
> In general, I think we should add a cleanup mechanism which cleans all {{Task}} specific
files after the {{Task}} has completed. The same applies to the {{TaskManager}}.
