After cancelling a job with a RocksDB backend all files are properly cleaned up, but the parent directories still exist and are empty:

{code}

+- StreamFlatMap_3_0
+- StreamFlatMap_3_3
+- StreamFlatMap_3_4
+- StreamFlatMap_3_5
+- StreamFlatMap_3_6
{code}

The number of empty folders varies between runs.
