             Summary: Make 
                 Key: YARN-4560
                 URL: https://issues.apache.org/jira/browse/YARN-4560
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
    Affects Versions: 2.8.0
            Reporter: Ray Chiang
            Assignee: Ray Chiang
            Priority: Trivial


If the YARN properties below are poorly configured:

{code}
yarn.scheduler.minimum-allocation-mb
yarn.scheduler.maximum-allocation-mb
{code}

The error message that shows up in the RM is:

{panel}
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)
{panel}

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