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

             Summary: Enable RLE during merge in TezMerger
                 Key: TEZ-3578
                 URL: https://issues.apache.org/jira/browse/TEZ-3578
             Project: Apache Tez
          Issue Type: Improvement

RLE is enabled at the mapper-side when DefaultSorter and PipelineSorter create IFile#Writer.
TezMerger at reducer-side also needs to set the flag properly during merge.
