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

             Summary: Tez should consider node information for computing failure fraction
                 Key: TEZ-4139
                 URL: https://issues.apache.org/jira/browse/TEZ-4139
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Rajesh Balamohan


When lots of downstream attempts fail to pull the information from source task, source task
is marked as failed and it is retried. Currently failure fraction is handled by looking at
unique task attempts from downstream. However, it should consider taking into account node
information for computing "failureFraction".
