> YARN-4270 introduced an additional log message that is currently at INFO level :
> {noformat}
> 2015-10-28 11:13:21,692 INFO
> org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FSAppAttemt:
> Reservation Exceeds Allowed number of nodes:
> app_id=application_1446045371769_0001 existingReservations=1
> totalAvailableNodes=4 reservableNodesRatio=0.05
> numAllowedReservations=1
> {noformat}
> It has been observed that the log message can totally swap the RM log file. This needs
to be reduced to DEBUG level.
