yarn-site.xml and aux-services
John Lilley 2013-06-04, 22:30
I notice the yarn-site.xml

  <property>
    <name>yarn.nodemanager.aux-services</name>
    <value>mapreduce.shuffle</value>
    <description>shuffle service that needs to be set for Map Reduce to run </description>
  </property>

Is this a general-purpose hook?
Can I tell yarn to run *my* per-node service?
Is there some other way (within the recommended Hadoop framework) to run a per-node service that exists during the lifetime of the NodeManager?
