Joep Rottinghuis commented on YARN-305:
---------------------------------------

Marking as critical. W/o this patch the RM log is filled with superfluous 
messages, masking real issues.
                
> Too many 'Node offerred to app:..." messages in RM

> 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
