Do we still need this with the index-based approach? We had this here
before to minimize how many packages we had to search because it was so time
consuming. What purpose does it serve now?
> Allow Stellar functions to be loaded from HDFS
> ----------------------------------------------
>
> Key: METRON-744
> URL: https://issues.apache.org/jira/browse/METRON-744
> Project: Metron
> Issue Type: New Feature
> Reporter: Casey Stella
>
> The benefit of Stellar is that adding new functionality is as simple as
> providing a Jar. This enables people who want to integrate with Metron to
> easy add enrichments or other functionality. The snag currently with this is
> that we provide a single jar, so all stellar functions that we have available
> must be dependencies of the main jar that drives the topology plus what local
> directories we can configure via the storm configs. This makes the process
> of adding 3rd party jars not as easy as it could be.
> Adjust the the following to additionally load classes from a location in HDFS
> /apps/metron/stellar using something like accumulo (
> https://accumulo.apache.org/blog/2014/05/03/accumulo-classloader.html)
> * Profiler topology
> * Parser topology
> * Enrichment topology
> * Enrichment Flat file loader
> * Enrichment MR loader
