Hi All, Never mind. Found the errors of my ways. Did not ssh keys setup for localhost.
Thanks -John From: John Beaulaurier -X (jbeaulau - ADVANCED NETWORK INFORMATION INC at Cisco) Sent: Thursday, November 08, 2012 10:01 AM To: '[email protected]' Subject: start-dfs.sh requesting password for user used to start daemon Hello, Apache Hadoop 0.20.203.0 (tarball) Java HotSpot (build 1.6.0_21-b07) I have a 4 datanode cluster sandbox I'm trying to startup, but when I initiate start.dfs.sh as the local user I created, , and after the namenode and all the datanodes start, the output stops and asks for the password for the local account that I'm using to run start-dfs.sh The same happens when I run stop.dfs.sh with all datanode daemons stopping except the namenode daemon. It does not stop due to the password requirement. SSH passphrase-less logon is functioning for the user from the namenode to all the datanodes.
