             Summary: Analyzer: Add an analyzer to find out scheduling misses in 1:1 edges
                 Key: TEZ-3805
                 URL: https://issues.apache.org/jira/browse/TEZ-3805
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Rajesh Balamohan
            Assignee: Rajesh Balamohan


When 1:1 edge is used, it would be helpful to find out whether downstream tasks ran on the same location provided in the hints by the runtime. 

One of the recent feature in upstream project (hive) used 1:1 edge. Instead of checking the logs, it would be useful to have an analyzer to churn out the details.
