-------------------------------
Summary: DAG-aware YARN task scheduler
Key: TEZ-3770
URL: https://issues.apache.org/jira/browse/TEZ-3770
Project: Apache Tez
Issue Type: New Feature
Reporter: Jason Lowe
Assignee: Jason Lowe
There are cases where priority alone does not convey the relationship between
tasks, and this can cause problems when scheduling or preempting tasks. If the
YARN task scheduler was aware of the relationship between tasks then it could
make smarter decisions when trying to assign tasks to containers or preempt
running tasks to schedule pending tasks.
