Weiwei Yang created YARN-8896:
---------------------------------
Summary: Limit the maximum number of container assignments per
heartbeat
Key: YARN-8896
URL: https://issues.apache.org/jira/browse/YARN-8896
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 3.0.0, 2.9.0
Reporter: Weiwei Yang
YARN-4161 adds a configuration
\{{yarn.scheduler.capacity.per-node-heartbeat.maximum-container-assignments}}
to control max number of container assignments per heartbeat, however the
default value is -1. This could potentially cause the CS gets stuck in the
while loop causing issue like YARN-8513. We should change this to a finite
number, e.g 100.
