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

             Summary: Ability to configure auxiliary services from HDFS-based JAR files
                 Key: YARN-1151
                 URL: https://issues.apache.org/jira/browse/YARN-1151
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
    Affects Versions: 2.1.0-beta
            Reporter: john lilley
            Priority: Minor


I would like to install an auxiliary service in Hadoop YARN without actually installing files/services
on every node in the system.  Discussions on the user@ list indicate that this is not easily
done.  The reason we want an auxiliary service is that our application has some persistent-data
components that are not appropriate for HDFS.  In fact, they are somewhat analogous to the
mapper output of MapReduce's shuffle, which is what led me to auxiliary-services in the first
place.  It would be much easier if we could just place our service's JARs in HDFS.
