The user and group list is separated by a blank. For e.g. "alice,bob users,wheel". A special value of "*" means all users are allowed.</description> </property> (1) http://hadoop.apache.org/common/docs/r0.20.2/service_level_auth.html Praveen On Tue, Jan 3, 2012 at 10:46 AM, praveenesh kumar <praveen...@gmail.com>wrote: > Hi, > > How can I allow multiple users to submit jobs in hadoop 0.20.205 ? > > Thanks, > Praveenesh >
