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

It has been observed that the log message can totally swap the RM log file.
This needs to be reduced to DEBUG level.
