SSH passwordless & Hadoop starup/shutdown scripts
Hello,
I had originally configured our dev cluster with SSH passwordless connectivity to the datanodes, but had a passphrase. I have
updated with no passphrase, and have copied the new public key to all datanodes updating their know_host files, and have tested
SSH with no passphrase from the namenode to all three datanodes with success. However when I initiate a stop-dfs.sh or
stop-mapred.sh as user running the current Hadoop processes the following is returned without ending the processes.
no namenode to stop
hostname,hostname,hostname,hostname: ssh: hostname,hostname,hostname,hostname: Name or service not knows
Can someone suggest where I should be looking for configuration issues?
Thank you
-John
