[jira] [Created] (TEZ-3222) Reduce messaging overhead for
auto-reduce parallelism case
Jonathan Eagles created TEZ-3222:
------------------------------------
Summary: Reduce messaging overhead for auto-reduce parallelism case
Key: TEZ-3222
URL: https://issues.apache.org/jira/browse/TEZ-3222
Project: Apache Tez
Issue Type: Bug
Reporter: Jonathan Eagles
Assignee: Jonathan Eagles
A dag with 15k x 1000k vertex may auto-reduce to 15k x 1. And while the data size is appropriate for 1 task attempt, this results in an increase in task attempt message processing of 1000x.
This jira aims to reduce the message processing in the auto-reduced task while keeping the amount of message processing in the AM the same or less.
