Sandeep More commented on KNOX-1094:
------------------------------------

Hello [~pbhagade@hortonworks.com] 
What message do you get with e.getMessage() ? It does log "NamingException" so that should be clear, although I do agree that wrapping the original exception would have been good as it would have preserved the stack trace.

I will move this to 0.15.0
