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.
