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

             Summary: Determine compression / compressionCodec at runtime to avoid burning CPU cycles
                 Key: TEZ-1067
                 URL: https://issues.apache.org/jira/browse/TEZ-1067
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan


- Based on the compressed data being written and its compression ratio, tez should be able to pick up the best compression codec for the job.  

- If the compression ratio is very poor, it should be possible to turn off compression as well (which could save good amount CPU cycles).
