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
