----------------------------------

             Summary: include a UUID/random name into the BlobKey
                 Key: FLINK-7140
                 URL: https://issues.apache.org/jira/browse/FLINK-7140
             Project: Flink
          Issue Type: Sub-task
          Components: Distributed Coordination, Network
    Affects Versions: 1.4.0
            Reporter: Nico Kruber
            Assignee: Nico Kruber


Currently, at the {{BlobServer}}, the id of a BLOB is only based on its contents. This may cause issues during cleanup of transient BLOBs with the same content (we don't do ref-counting on a per-blob basis anymore) or at the rare occasion of a hash collision.
