> nodetool status command always displays the first token for a node even if using vnodes.
The defect is only reproduced on version 2.0.7. 
> With the same configuration 2.0.7 displays:

> The problem seems to be in NodeCmd.java the check for vnodes.
> In the print() method there is a check 
> // More tokens then nodes (aka vnodes)?
>             if (tokensToEndpoints.values().size() < tokensToEndpoints.keySet().size())
>                 isTokenPerNode = false;
> while in 2.0.6 the same code was:
> // More tokens then nodes (aka vnodes)?
>             if (new HashSet<String>(tokensToEndpoints.values()).size() < tokensToEndpoints.keySet().size())
>                 isTokenPerNode = false;
> In 2.0.7 this check is never true as values collection is always equal by size with key
set size.
