    Description

      If the YARN properties below are poorly configured:

      yarn.scheduler.minimum-allocation-mb
yarn.scheduler.maximum-allocation-mb

      The error message that shows up in the RM is:

      2016-01-07 14:47:03,711 FATAL org.apache.hadoop.yarn.server.resourcemanager.ResourceManager: Error starting ResourceManager
      org.apache.hadoop.yarn.exceptions.YarnRuntimeException: Invalid resource scheduler memory allocation configuration, yarn.scheduler.minimum-allocation-mb=-1, yarn.scheduler.maximum-allocation-mb=-3, min should equal greater than 0, max should be no smaller than min.
      at org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FairScheduler.validateConf(FairScheduler.java:215)

      While it's technically correct, it's not very user friendly.
