> Inconsistent file storage behavior in FileCache
> -----------------------------------------------
>
> Key: FLINK-9382
> URL: https://issues.apache.org/jira/browse/FLINK-9382
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Task
> Affects Versions: 1.6.0
> Reporter: Chesnay Schepler
> Priority: Major
> Labels: stale-major
>
> The file storage behavior in the {{FileCache}} is inconsistent and depends
> whether we're accessing a file or zipped folder.
> In case of a file we return the file returned from the
> {{PermanentBlobService}} as is, in this case the blobserver takes care of
> deleting the file _at some point_.
> In case of a directory (that is implicitly zipped!) we extract the zip into a
> separate storage directory and delete the zip afterwards (the deletion in
> particular is questionable as it interferes with the blob server).
> The underlying issue to me is that the responsibilities between the
> {{PermanentBlobService}} and {{FileCache}} aren't clearly laid out, and they
> actually seem a bit redundant.
> We may want to change the FIleCache to be a thin wrapper around the
> {{PermanentBlobService}} that only takes care of unzipping directories and
> setting executable flags.
