> Project: Flink
> Issue Type: Bug
> Components: Client, Local Runtime
> Affects Versions: 1.6.0
> Reporter: Chesnay Schepler
> Assignee: Dawid Wysakowicz
> Priority: Blocker
> Fix For: 1.6.0
>
>
> 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.
