Subject Re: Local blobStore not freed

Hi Dan,

Said "The files are removed after a restart of the process", it sounds Flink
cleaned up blobs properly. From your description I don't understand clearly
in which case/situation you expected Flink deleted blobs but it doesn't.

Could you describe the difference between 1.4.2 and 1.7.2/1.8.0 in detail?
Especially what moment exactly you want blobs to be deleted and it was not.
