             Summary: Dist Cache: Randomize the order of blobs downloaded
                 Key: STORM-881
                 URL: https://issues.apache.org/jira/browse/STORM-881
             Project: Apache Storm
          Issue Type: Improvement
            Reporter: Robert Joseph Evans


For a large topology we can easily do a DDOS on a single node if all of the supervisors are in sync as they try to download blobs at the same time.  It would be good to randomize the order of the blobs being downloaded so we are not likely to all be hitting the same nodes at the exact same time.
