Hi Starry, What is the content of your 'slaves' file in the hadoop/conf directory of your master node? It should say something like:
localhost us...@server2 us...@server3 us...@server4 This should let the start-up scripts try and login using the proper users. Hope that helps, Menno -----Oorspronkelijk bericht----- Van: Starry SHI [mailto:starr...@gmail.com] Verzonden: maandag 4 mei 2009 10:53 Aan: core-user@hadoop.apache.org Onderwerp: How to configure nodes with different user account? Hi, all. I am new to Hadoop and I have a question to ask~ I have several accounts located in different linux servers (normal user privilege, no admin authority), and i want to use them to form a small cluster to run Hadoop applications. However, the usernames for these accounts are different. I want to use shared key to connect all the nodes, but I failed after several attempts. Is it possible to connect all of them via different account? For example, I have 3 account: us...@server1, us...@server2, us...@server3. After assigning authorized keys, I can use "ssh us...@server2" without input the password. But when I start hadoop, I was asked to input the password for us...@server2 (when I have already logged in as user1). Can my problem be solved easily? I wish to get your help soon. Thank you for all your attention and help! Best regards, Starry
