      Description

      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.
