----------------------------------
Summary: FS checkpoints leave empty directory
Key: FLINK-5009
URL: https://issues.apache.org/jira/browse/FLINK-5009
Project: Flink
Issue Type: Bug
Reporter: Ufuk Celebi
Run a job with FS state backend and enable checkpointing.
Cancel the job.
In the checkpoint directory, you have an empty directory with the job ID
({{:checkpointDir>/:jobID}}).
The {{FsCheckpointStreamFactory}} creates this directory, but it is never
called to clean it up again (in general, the stream factories have no hooks to
do clean up).
