             Summary: Fetch Multiple Partitions from the Shuffle Handler
                 Key: TEZ-3361
                 URL: https://issues.apache.org/jira/browse/TEZ-3361
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Jonathan Eagles


Provide an API that allows for fetching multiple partitions at once from a 
single upstream task. This is to better support auto-reduce parallelism where a 
single downstream task is impersonating several (possibly?) consecutive 
downstream tasks.
