>
> 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.
