Casey Stella created METRON-744:
-----------------------------------
Summary: 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
