[GitHub] [accumulo-examples] jmark99 opened a new issue, #113: Dirlist example throws exceptions during execution
jmark99 opened a new issue, #113:
URL: https://github.com/apache/accumulo-examples/issues/113
When running the Dirlist example and executing
`./bin/runex dirlist.Viewer....`
exceptions are thrown in the terminal window. The Viewer GUI appears to work properly but the exceptions should be examined more closely and resolved if possible.

@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:

@jmark99 Can you be more specific on what exception you see in the terminal? The exceptions I ran into were only Auth issues. One for user `username` which did not exist. Unsure if part of the example should be creating the user on its own or not.
The other exception involved when running `./bin/runex dirlist.Viewer....` was the root user who didn't have the auth either. Giving root the auth seemed to resolve the exception but my file viewer didn't seem to work correctly.

After coming back to this, I have been able to reproduce the error. I am still looking for a solution but my guess is the client that was used to create the viewer was closed by the try-with-resources block that was used to create it.
