-------------------------------------
Summary: ContainerReporter requests AM for getTask too frequently
(causing pressure on AM side)
Key: TEZ-1589
URL: https://issues.apache.org/jira/browse/TEZ-1589
Project: Apache Tez
Issue Type: Bug
Reporter: Rajesh Balamohan
Assignee: Rajesh Balamohan
Min time to wait before a task requests AM for another task is set to 200 ms.
As per ContainerReporter->call() logic, it would be invoked every 10ms until we
reach 200ms.
This wouldn't be much of a problem for small jobs. But for large jobs with
many tasks, this will cause pressure on AM.
