> Project: Flink
> Issue Type: Improvement
> Components: Distributed Coordination, Network
> Affects Versions: 1.4.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
>
> Currently, the BLOB server and cache processes (temporarily) stash incoming
> files into their local file system in the directory given by the
> {{blob.storage.directory}} configuration property. If this property is not
> set or empty, it will fall back to {{java.io.tmpdir}}.
> Instead, in a Mesos/YARN environment, we could use the temporary directories
> they assigned to the Flink job which are not only the proper folder to use,
> but may also offer some more space.
