----------------------------------
Summary: Use Mesos/YARN temp directories as fallback for BlobServer/Cache temp directories
Key: FLINK-8279
URL:
https://issues.apache.org/jira/browse/FLINK-8279 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.
