             Summary: Avoid buffer copies by passing RLE flag to TezMerger from PipelinedSorter
                 Key: TEZ-3777
                 URL: https://issues.apache.org/jira/browse/TEZ-3777
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan


RLE information computed in pipelinedSorter can be passed on to {{TezMerger.merge}} in  {{PipelinedSorter::flush}}. Depending on dataset, this can save lot of data copies.
