Josh Elser commented on ACCUMULO-3424:
--------------------------------------
Looking at the history, it looks like some changes were made in ACCUMULO-1323 and maybe were
misintepreted in ACCUMULO-1478? I can't see a reason for enforcing that we always have token
properties from the initial change. If anyone has more context, please let me know.

> Key: ACCUMULO-3424
> URL: https://issues.apache.org/jira/browse/ACCUMULO-3424
> Project: Accumulo
> Issue Type: Bug
> Components: shell
> Affects Versions: 1.6.0, 1.6.1
> 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.
