   @Manno15 I have just been running the example as the root user and providing a path to some subset of my Accumulo dev directory as the argument for the Ingest command. I'm sure the documentation could use some more clarity. 
   
   Providing the root user with the exampleVis auth then allows me to scan the tables. The exceptions I'm referring to occur when I run the Viewer program. The Viewer displays the data correctly and as expected, but exceptions are written to the console terminal that called the Viewer program. It would be nice to resolve them. The following is an example:
   
   `
   Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: This client was closed.
