> Running fair scheduler YARN shows that RM has lots of messages like the below.
> {noformat}
> INFO org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.AppSchedulable: Node
offered to app: application_1357147147433_0002 reserved: false
> {noformat}
> They dont seem to tell much and same line is dumped many times in RM log. It would be
good to have it improved with node information or moved to some other logging level with enough
debug information
