Hi All, I trying to install Hadoop in distributed mode over Two Mac OS X 10.6.8 machines.
I have configured 1) One as a Master ( plays role of both Name node and Data Node) 2) Second as a Slave ( Only date node) I have give same name to both Machines and they have Admin access. pluto ( for both Master and Slave). and generated ssh key pair through this way Master:~ mediaadmin$ ssh-keygen -t rsa -P " " Generating public/private rsa key pair. Enter file in which to save the key (/Users/mediaadmin/.ssh/id_rsa): /Users/mediaadmin/.ssh/id_rsa already exists. Overwrite (y/n)? y Your identification has been saved in /Users/mediaadmin/.ssh/id_rsa. Your public key has been saved in /Users/mediaadmin/.ssh/id_rsa.pub. The key fingerprint is: 32:0f:be:7a:ea:44:a1:4a:b6:b1:85:3f:1f:56:48:4b mediaadmin@Master The key's randomart image is: +--[ RSA 2048]----+ | | | | | .E | | ..o.o | | =...o+.S | |o.*. ..= | |.o o.o. . | | .+ o. | | .+=. | +-----------------+ Copy to home Master:~ mediaadmin$ cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys and copy to Slave Node as mediaadmin$ cat ~/.ssh/id_rsa.pub | ssh pluto@Slave 'cat >> ~/.ssh/authorized_keys' Login to Slave node Master:~ mediaadmin$ ssh pluto@Slave Last login: Thu Oct 25 18:54:15 2012 from 10.203.33.80 and Log out plutos-iMac:~ pluto$ exit logout Connection to Slave closed. Login to Master node (here it asks for password) Master:~ mediaadmin$ ssh Master Password: Last login: Thu Oct 25 19:03:27 2012 from master HERE COMES THE ISSUE when I run start-dfs.sh, its asks for password and I did enter the pass word of Master but i didn't accept. Master:~ mediaadmin$ start-dfs.sh starting namenode, logging to /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-namenode-Master.out Password:Password: Password: Password: Slave: Permission denied (publickey,keyboard-interactive). Password: Master: starting datanode, logging to /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-datanode-Master.out Password: Master: starting secondarynamenode, logging to /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-secondarynamenode-Master.out When I enter password of Slave then it again goes like this. Master:~ mediaadmin$ start-dfs.sh starting namenode, logging to /HADOOP/hadoop-0.20.2/bin/../logs/hadoop-mediaadmin-namenode-Master.out Password:Password: Password: Password: Password: Password: Master: Permission denied (publickey,keyboard-interactive). Slave: Permission denied (publickey,keyboard-interactive). Password: Password: Password: Master: Permission denied (publickey,keyboard-interactive). Please suggest me where I am going wrong, and why is asking for password when I configured it as password less SSH, where I doing mistake in SSH or some thing else.
