Ран bin/hdfs namenode -format, который прошел нормально без каких-либо ошибок, а затем, наконец, запустил sbin/start-dfs.sh, что не дает мне ошибок со следующим журналом

Когда я go до localhost:50070 я ничего не получаю (сайт не может быть достигнут), и когда я нажимаю jps, я не вижу никакого namenode или вторичного namenode выполняется.
Что я сделал?
Есть что-то, что нужно настроить, или что-то, что я скучаю г?
Заранее спасибо!
