From: =?GB2312?B?v6HGvbbC?= To: general@hadoop.apache.org Content-Type: multipart/alternative; boundary=0016e6dd863c2d7bcd04a66a1b1c X-Virus-Checked: Checked by ClamAV on apache.org --0016e6dd863c2d7bcd04a66a1b1c Content-Type: text/plain; charset=ISO-8859-1 Hello all, I setup a hadoop cluster (0.20.2 distribution), and start it with one user on master node. When I switch to another user, I even cannot see any processes for hadoop (use jps command) which means I cannot submit job into this cluster user another user account. I see a lot of articles saying that hadoop support multi-tenancy, can anyone tell me how to configure it? Thanks a lot! Best Regards, J.P --0016e6dd863c2d7bcd04a66a1b1c--
