--------------------------------

             Summary: Remove obsolete entries from yarn-default.xml
                 Key: YARN-2460
                 URL: https://issues.apache.org/jira/browse/YARN-2460
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.5.0
            Reporter: Ray Chiang
            Priority: Minor


The following properties are defined in yarn-default.xml, but do not exist in 
YarnConfiguration.

  mapreduce.job.hdfs-servers
  mapreduce.job.jar
  yarn.ipc.exception.factory.class
  yarn.ipc.serializer.type
  yarn.nodemanager.aux-services.mapreduce_shuffle.class
  yarn.nodemanager.hostname
  yarn.nodemanager.resourcemanager.connect.retry_interval.secs
  yarn.nodemanager.resourcemanager.connect.wait.secs
  yarn.resourcemanager.amliveliness-monitor.interval-ms
  yarn.resourcemanager.application-tokens.master-key-rolling-interval-secs
  yarn.resourcemanager.container.liveness-monitor.interval-ms
  yarn.resourcemanager.nm.liveness-monitor.interval-ms
  yarn.timeline-service.hostname
  yarn.timeline-service.http-authentication.simple.anonymous.allowed
  yarn.timeline-service.http-authentication.type

Presumably, the mapreduce.* properties are okay.  Similarly, the 
yarn.timeline-service.* properties are for the future TimelineService.  
However, the rest are likely fully deprecated.

Submitting bug for comment/feedback about which other properties should be kept 
in yarn-default.xml.
