Subject [jira] [Created] (TEZ-3803) Tasks can get killed due to insufficient progress while waiting for shuffle inputs to complete
Date Fri, 21 Jul 2017 11:40:02 GMT
Kuhu Shukla created TEZ-3803:
--------------------------------

             Summary: Tasks can get killed due to insufficient progress while waiting for
shuffle inputs to complete
                 Key: TEZ-3803
                 URL: https://issues.apache.org/jira/browse/TEZ-3803
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Kuhu Shukla
            Assignee: Kuhu Shukla
            Priority: Critical


In a scenario where a downstream task has no slow start and gets started before all its shuffle
inputs are done, the task can timeout as the wait does not notify progress( set the "progress
is being made bit") like it does in MapReduce.
