That's not the case, I've even removed hadoop-fairscheduler-0.20.2-cdh3u2.jar from hadoop lib folder and fair-scheduler.xml from hadoop conf folder and it didn't help... Any ideas?

I have concern with my 3 node cluster, I run capacity scheduler with 4 queues and one has 30% of cluster resources, the problem is that when I schedule a job, all tasks are assigned to one single node which takes all of it's mappers and works quite slow. Are there any settings for mapred/capacity scheduler to assign mappers on all nodes by even number of tasks? 2. I've set my capacity-scheduler.xml settings "mapred.capacity-scheduler.queue.job1.capacity" for all queues as wanted but jobtracker doesn't reallocate resources from free queues if only one is working, why? Thanks, Marek M.
