Re: New to Hadoop-SSH communication
Thank you Tariq.

I am using  the same username on both the machines and when i try to copy a
file master to slave just to make sure SSH is working fine, The file is
copying into master itself not an slave machine.

  scp -r /usr/local/somefile hduser@slave:/usr/local/somefile

Any suggestions...
Thanks
Annt
