[jira] [Created] (TEZ-3388) Provide error information in shuffle response header

Bikas Saha created TEZ-3388:
-------------------------------

             Summary: Provide error information in shuffle response header
                 Key: TEZ-3388
                 URL: https://issues.apache.org/jira/browse/TEZ-3388
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Bikas Saha


In MR shuffle, if any partition has an error then the reader gets an exception while reading the response stream and loses all the data for all partitions. Instead if the shuffle response header had more metadata then errors could be handled more efficiently.
