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

     [ https://issues.apache.org/jira/browse/TEZ-3388?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bikas Saha updated TEZ-3388:
----------------------------
    Description: 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. See YARN-1773 for history.  (was: 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.)
