Do you need a separate us...hello, I had a question:<br />Do you need a separate user for each service? (hdfs, mapred) or can these be started as one user say, hduser. From what I understand it doesn't matter what user you start services as, as long as you kinit properly using keytabs for each service. Am I wrong in this logic? I am getting failed connections from my keytabs when trying to start the namenode and I have tried starting it as hdfs user, but that only leads to permission issues or namenode class not found exaceptions. Any suggestions would be much appreciated.<br /><br />Thanks you Anonymoushttps://www.blogger.com/profile/09105130595172291291noreply@blogger.com
