> In FLINK-8620 the distributed cache was modified to the distribute files via the blob store, instead of downloading them from a distributed filesystem.
> Previously, taskmanagers would download requested files from the DFS. Now, they retrieve it form the blob store. This requires the client to preemptively upload all files used with distributed cache.
> As a result it is no longer possible to use the distributed cache for files that reside in a cluster-internal DFS, as the client cannot download it. This is a regression from the previous behavior and may break existing setups.
