Description:

def fail(self, group, message):
        '''Mark the particular job as failed, with the provided type, and a
        more specific message. By `type`, we mean some phrase that might be
        one of several categorical modes of failure. The `message` is
        something more job-specific, like perhaps a traceback.

        This method should __not__ be used to note that a job has been dropped
        or has failed in a transient way. This method __should__ be used to
        note that a job has something really wrong with it that must be
        remedied.

        The motivation behind the `type` is so that similar errors can be
        grouped together. Optionally, updated data can be provided for the job.
        A job in any state can be marked as failed. If it has been given to a
        worker as a job, then its subsequent requests to heartbeat or complete
        that job will fail. Failed jobs are kept until they are canceled or
        completed. __Returns__ the id of the failed job if successful, or
        `False` on failure.'''
        logger.warn('Failing %s (%s): %s', self.jid, group, message)
        return self.client('fail', self.jid, self.client.worker_name, group,
            message, json.dumps(self.data)) or False
