我需要破解单个节点hadoop“集群”（cloudera psuedo-distributed）才能够远程访问它。 我已经成功安装了hadoop，并且已经将configuration中的本地主机标识符更新为本机的IP地址。 我可以运行hadoop fs -ls /而且一切都很好。 我创build了一个密码短语，我可以ssh到Hadoop机器。
连接build立与：
ssh -vvvv -i .ssh/hadoop_rsa -o ConnectTimeout=10 -o ServerAliveInterval=60 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null-N -D 6666 [email protected]
当我在远程机器上运行hadoop fs -ls /时，ssh输出是：
debug1: Connection to port 6666 forwarding to socks port 0 requested. debug2: fd 6 setting TCP_NODELAY debug2: fd 6 setting O_NONBLOCK debug3: fd 6 is O_NONBLOCK debug1: channel 2: new [dynamic-tcpip] debug2: channel 2: pre_dynamic: have 0 debug2: channel 2: pre_dynamic: have 4 debug2: channel 2: decode socks5 debug2: channel 2: socks5 auth done debug2: channel 2: pre_dynamic: need more debug2: channel 2: pre_dynamic: have 0 debug2: channel 2: pre_dynamic: have 10 debug2: channel 2: decode socks5 debug2: channel 2: socks5 post auth debug2: channel 2: dynamic request: socks5 host 151.84.13.73 port 8020 command 1 channel 2: open failed: administratively prohibited: open failed debug2: channel 2: zombie debug2: channel 2: garbage collecting debug1: channel 2: free: direct-tcpip: listening port 6666 for 151.84.13.73 port 8020, connect from 127.0.0.1 port 50703, nchannels 3 debug3: channel 2: status: The following connections are open:
围绕administratively prohibited我确保8020和8021港口在哈托普机场（151.84.13.73）上开放，
sudo ufw status Status: active To Action From -- ------ ---- 22/tcp ALLOW Anywhere munin-node ALLOW Anywhere 5666/tcp ALLOW Anywhere 8021 ALLOW Anywhere 8020 ALLOW Anywhere
和
sudo iptables -L . . ACCEPT udp -- anywhere anywhere udp dpt:8021 ACCEPT tcp -- anywhere anywhere tcp dpt:8020 ACCEPT udp -- anywhere anywhere udp dpt:8020 .
channel 2: open failed其他原因是什么channel 2: open failed ？
编辑1：似乎hadoop正在侦听正确的端口：

而nmap显示两个端口都打开。
有没有其他authentication正在进行？
