        Full output is the kill usage manual.

        -probably best for the methods to do some parameter checking, possbly raising NPEs to track this down

        Is this happening with trunk(even after HADOOP-5488) ? Would you please provide the stack trace ?

        I'm going to close this as stale. If this is still an issue, probably better to open a new jira.
