      Description

      What happens is that the number of reducers ramp up until they occupy all of the job's containers, at which point the maps no longer make any progress and the job hangs.

      When the same job is run with the CapacityScheduler it succeeds, so this looks like a FifoScheduler bug.

          The code in RMContainerAllocator is meant to handle this case by ramping up the number reducers as maps finish. However, there seems to be something fishy about the total amount of memory available to the job. Compare

          2012-05-24 16:47:25,803 INFO [RMCommunicator Allocator] org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator: completedMapPercent 0.3 totalMemLimit:63488 finalMapMemLimit:44442 finalReduceMemLimit:19046 netScheduledMapMem:117760 netScheduledReduceMem:15360

          The first says that there is 63488 MB of memory, the second 32768 MB (these numbers stay the same throughout the job). So what could be happening is that the allocator slowly ramps up the number of reducers until they use up 32768 MB (32 slots at 1024MB apiece) thinking that there is still memory available when there isn't. The code has some confusion between the terms 'available resource', 'headroom', and 'cluster resource' - i.e. it's not clear if available resource is a total, or just what's not in use. RMContainerAllocator.getMemLimit() suggests the latter, while the FifoScheduler has the line application.setHeadroom(clusterResource) which suggests that it's a fixed total.

          The problem is that FifoScheduler always sets the application headroom to be the entire set of cluster resources, without taking into account any containers that have been assigned. In some cases, like the terasort case mentioned in the JIRA, this leads to the reducer tasks using all the cluster resources before the map tasks have finished, resulting in deadlock.

          Attached is a fix with a unit test.

          Tom,

          Thanks for the patch.

          I had a couple of questions though, please correct me if I understand it wrong.

          • Just realized that the application headroom is being set after the for loop; shouldn't we update it within the for loop itself so that subsequent iterations (applications) would see the updated resources.
          • If number of applications makes a difference, the test should probably have more applications before we trigger node update.

          Thanks for taking a look at the patch Karthik.

          > Just realized that the application headroom is being set after the for loop; shouldn't we update it within the for loop itself so that subsequent iterations (applications) would see the updated resources.

          It's the other way round: the headroom should be set after the assignments have been made in the loop (in the call to assignContainersOnNode).

          > If number of applications makes a difference, the test should probably have more applications before we trigger node update.

          Good idea - I updated the test to have two applications.
