Description

Accepted allocation proposal and reserved container logs are two exceedingly frequent events. Numerous user reported that these log entries had quickly filled the logs on a busy cluster and seen these entries only as noise.

It would be worthwhile to reduce the log level of these entries to DEBUG level.

Examples:

2021-10-30 02:28:57,409 INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler: Allocation proposal accepted
2021-10-30 02:28:57,439 INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.common.fica.FiCaSchedulerApp: Reserved container=container_1635478503131_0069_01_000078, on node=host: node:8041 #containers=1 available=<memory:1835, vCores:3> used=<memory:3072, vCores:1> with resource=<memory:3072, vCores:1>
