Xiaogang Shi commented on FLINK-5925:
-------------------------------------
+1 for the cleanup mechanism. Each component (e.g. {{TaskManager}}, {{Task}}
and {{StateBackend}}) should be given a working directory and it should place
all its files in that directory. When the component exists, we can simply
delete the directory to clean unused files.

> Key: FLINK-5925
> URL: https://issues.apache.org/jira/browse/FLINK-5925
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.2.0, 1.3.0
> Reporter: Till Rohrmann
>
> 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}}.
