Arun, Please do not cross-post to multiple lists. Lets continue this on mapreduce-user@ alone.
Your problem isn't the job submission here, but your Capacity Scheduler configuration. For every queue you configure, you need to add in capacities: Please see the queue properties documentation at http://hadoop.apache.org/common/docs/current/capacity_scheduler.html#Queue+properties for the vital configs required in additional to mapred.queue.names. Once done, you should have a fully functional JobTracker! On Fri, Sep 16, 2011 at 10:17 AM, arun k <arunk...@gmail.com> wrote: > Hi all ! > > Harsh !
