[jira] [Created] (PIG-4348) Enhance Tez AM size estimation

Rohini Palaniswamy created PIG-4348:
---------------------------------------

             Summary: Enhance Tez AM size estimation
                 Key: PIG-4348
                 URL: https://issues.apache.org/jira/browse/PIG-4348
             Project: Pig
          Issue Type: Sub-task
            Reporter: Rohini Palaniswamy


 Currently Tez AM size is increased upto 4G automatically based on total number of tasks.  Also need to take into account a lot of other factors like vertices, number of shuffle edges possible, etc. 

 A job with 17390 tasks for which memory was increased to 2G and container size to 2.5G still failed with OOM as it had 38 vertices.
