I wrote the below code

    def _train(iter):
        mgr = _get_manager(cluster_info, util.get_ip_address(), os.getppid())
        queue = mgr.get_queue(qname)
        state = str(mgr.get('state'))
        logging.info('mgr.state={0}'.format(state))
        terminating = (state == "'terminating'")
        if terminating:
            logging.info('mgr    is    terminating,    skipping    partition')
            count = 0
            for item in iter:
                count += 1
            logging.info('Skipped    {0}    items    from    partition'.format(count))
        else:
            logging.info('Feeding    partition    {0}    into    {1}    queue    {2}'.format(iter, qname, queue))
            count = 0
            for item in iter:
                count += 1
                queue.put(item, block=True)
            queue.join()
            logging.info('Processed    {0}    items    in    partition'.format(count))
        state = str(mgr.get('state'))
        terminating = (state == "'terminating'")
        if terminating:
            try:
                logging.info('TFSparkNode:    requesting    stop')
                client = reservation.Client(cluster_meta['server_addr'])
                client.request_stop()
                client.close()
            except Exception as e:
                logging.debug('Error    while    requesting    stop:    {0}'.format(e))
        return [terminating]
    return _train

What's a good function header?
