    Description

      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.
