Hadoop 没有密码的ssh localhost不适用于Mac OS X 10.9.1

我正在尝试在我的mac上安装hadoop，其先决条件是能够在不使用密码的情况下通过ssh连接到本地主机。以下是我采取的步骤

osxltrsingh:~ rsingh$ rm -rf .ssh/
osxltrsingh:~ rsingh$ sudo systemsetup -setremotelogin on
Password:
setremotelogin: remote login is already On.
osxltrsingh:~ rsingh$ ssh-keygen -t rsa -P ""
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/rsingh/.ssh/id_rsa): 
Created directory '/Users/rsingh/.ssh'.
Your identification has been saved in /Users/rsingh/.ssh/id_rsa.
Your public key has been saved in /Users/rsingh/.ssh/id_rsa.pub.
The key fingerprint is:
5e:24:e9:f7:de:bc:73:29:63:da:8d:f2:00:0b:07:f1 rsingh@osxltrsingh.corp.appdynamics.com
The key's randomart image is:
+--[ RSA 2048]----+

|        .. ..   .|

+-----------------+
osxltrsingh:~ rsingh$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
osxltrsingh:~ rsingh$ ssh localhost
The authenticity of host 'localhost (::1)' can't be established.
RSA key fingerprint is d2:c2:ed:68:d9:7c:d0:11:de:72:51:ff:49:4f:aa:23.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (RSA) to the list of known hosts.

如您所见，它仍然要求输入密码。这里有我遗漏的东西吗。我试图在谷歌上找到问题，但我不知道我做错了什么。非常感谢您的帮助

ssh的详细输出是

，以从ssh获得更详细的输出。@Jeff，我添加了verbose问题本身的输出。
