-------------------------------
Summary: Improve response time of internal preemption
Key: TEZ-1742
URL: https://issues.apache.org/jira/browse/TEZ-1742
Project: Apache Tez
Issue Type: Task
Reporter: Bikas Saha
Assignee: Bikas Saha
Tez YARN Task Scheduler currently preempts 1 running task at a time when a
higher priority task is waiting and there are no available resources. When a
large number of higher priority tasks are pending then it can take a long time
to preempt the required number of lower priority tasks.
