             Summary: Create a classpath-isolating classloader for the Metron topologies
                 Key: METRON-2286
                 URL: https://issues.apache.org/jira/browse/METRON-2286
             Project: Metron
          Issue Type: Improvement
            Reporter: Michael Miklavcic


This would be an improvement based on existing working started in https://issues.apache.org/jira/browse/METRON-744.

https://accumulo.apache.org/blog/2014/05/03/accumulo-classloader.html

Storm provides no classpath isolation in its topology runtime, so it is a very common occurrence to run into version compatibility problems from libraries such as: Guava, Jackson, SLF4J, and Log4j between kafka, hadoop, hbase, and Storm.
