    Description

      YARN-4270 introduced an additional log message that is currently at INFO level :

      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
      

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