             Summary: Custom Tez runtime unordered output buffer size depending 
on operator pipeline
                 Key: HIVE-21329
                 URL: https://issues.apache.org/jira/browse/HIVE-21329
             Project: Hive
          Issue Type: Improvement
          Components: Tez
            Reporter: Jesus Camacho Rodriguez
            Assignee: Jesus Camacho Rodriguez


For instance, if we have a reduce sink operator with no keys followed by a 
Group By (merge partial), we can decrease the output buffer size since we will 
only produce a single row.
