[jira] [Created] (TEZ-4005) Add Host-Source input penalties to Unordered Shuffle

Kuhu Shukla created TEZ-4005:
--------------------------------

             Summary: Add Host-Source input penalties to Unordered Shuffle
                 Key: TEZ-4005
                 URL: https://issues.apache.org/jira/browse/TEZ-4005
             Project: Apache Tez
          Issue Type: Task
    Affects Versions: 0.9.1
            Reporter: Kuhu Shukla


Ordered shuffle has a mechanism to penalize hosts and try exponential waits for retrying. Unordered case is missing this feature. Would be really useful to add this and make shuffle policies consistent.
