Kevin Minder commented on KNOX-502:
-----------------------------------

After further investigation, the above audit log sample isn't really wrong it 
is just misleading.  I'm making a fix to add auditing to the servlet in Knox 
that does the forwarding for the default topology.  The results in an audit log 
that looks like this so that it is clear that a forward occurred hopefully 
avoiding any confusion.

> Currently there is no Knox level diagnostic or audit information produced for 
> 404s.  This has been making it difficult for users to self diagnose 
> mismatches between their perception of a cluster name and a topology name.  
> We should provide better diagnostics here to help the users figure out what 
> the problem is.
