> 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:
