------------------------------------

             Summary: Token class option always requires token property
                 Key: ACCUMULO-3424
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3424
             Project: Accumulo
          Issue Type: Bug
          Components: shell
    Affects Versions: 1.6.1, 1.6.0
            Reporter: Josh Elser
            Assignee: Josh Elser
             Fix For: 1.6.2, 1.7.0


In testing out ACCUMULO-2815, I attempted to manually provide a KerberosToken to authenticate myself and then launch the shell, but ran into an issue. The KerberosToken (in its current state) needs no options: it's wholly functional on its own.

{{accumulo shell -tc org.apache.accumulo.core.client.security.tokens.KerberosToken}}  gives an error

{noformat}
2014-12-16 11:41:09,712 [shell.Shell] ERROR: com.beust.jcommander.ParameterException: Must supply either both or neither of '--tokenClass' and '--tokenProperty'
{noformat}

And providing an empty option just prints the help message {{accumulo shell -tc org.apache.accumulo.core.client.security.tokens.KerberosToken -l ""}}

I'm guessing the latter is just how the JCommander DynamicParameter is implemented, but I don't see a reason why every authentication *must* have some properties provided to it.
