[jira] [Created] (TEZ-1448) Make WeightedScalingMemoryDistributor as the default memory distributor

Rajesh Balamohan created TEZ-1448:
-------------------------------------

             Summary: Make WeightedScalingMemoryDistributor as the default memory distributor
                 Key: TEZ-1448
                 URL: https://issues.apache.org/jira/browse/TEZ-1448
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan


Currently Tez uses ScalingAllocator; WeightedScalingMemoryDistributor provides better control over ScalingAllocator.  

In certain DAG executions, response time improvements of over 6% have been observed at 10 TB scale and ~26% runtime improvement in memory intensive reducers.
