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

             Summary: Progressive allocation of buffers for Unordered Partitioned Output
                 Key: TEZ-2951
                 URL: https://issues.apache.org/jira/browse/TEZ-2951
             Project: Apache Tez
          Issue Type: Improvement

Similar to TEZ-2244. In the case of UnorderedPartitionOutput - the default is to use 2 buffers. This can be changed to a higher value when using pipelined shuffle - and have memory allocated only when required.
