    The Metron version is embedded in this class name.  Also, the path for the Indexing `metron-deployment/packaging/ambari/src/main/resources/common-services/INDEXING/0.2.0BETA/...`
includes the Metron version.  
    
    How will we handle this when we bump Metron versions?  Is there no better way to handle
this?  I know we have to play within the sandbox provided by Ambari.  Is this an Ambari-imposed
pain point?
    
    Everything else looks great BTW.  Very easy to read code.
