Subject Fair scheduler not assigning tasks
Date Mon, 20 Jan 2014 09:30:54 GMT
I've been using Fair Scheduler with Hadoop 1.0.4 for f few months now with
no issues what so ever.
All of a sudden I have a problem where jobs are in status UNASSIGNED. Jobs
submitted are pending for map/reduce slots although the cluster resources
are free.
In some of the pools only map slots are available, in others only reduce
slots and in some nothing is.
If I change the jobs' pool or upgrade it's priority it sorts itself.....

I see nothing in JobTracker / TaskTracker logs.
Any ideas ?
