hadoop - 连接已被127.0.0.1关闭

Question

我在这里使用hadoop框架。我之前从以下站点安装了hadoop:http://ebiquity.umbc.edu/Tutorials/Hadoop/05%20-%20Setup%20SSHD.html。它对我有用。但是现在我必须将其安装在另一台PC中。我尝试了相同的步骤但被卡在这里

在命令:ssh localhost
它显示了我错误:连接被127.0.0.1关闭

我曾尝试过Google多次，但无法获得。任何 body 都可以帮助:

我在Windows 7中使用cygwin在这里工作:
错误提示在这里:

$ ssh localhost
The authenticity of host 'localhost (127.0.0.1)' can't be established.
ECDSA key fingerprint is 37:80:a5:b5:29:29:35:ee:f3:7c:67:28:d0:27:9b:d4.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.

使用ssh -v localhost后:

终于我明白了，这是因为我的Avast防病毒软件。它阻止了本地服务器打开。我将其卸载并开始运行。愿它会帮助某人。
