+1 (binding) I downloaded the src tar ball, built it with the native bits enabled, started up a little cluster, and ran some sample jobs. Things worked as expected. I also verified the signatures on the source artifact.
I did bump into one little issue, but I don't think it should be considered a blocker. When I first tried to start up the RM, it failed to start with this error: 13/02/08 16:00:31 FATAL resourcemanager.ResourceManager: Error starting ResourceManager java.lang.IllegalStateException: Queue configuration missing child queue names for root at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.parseQueue(CapacityScheduler.java:328) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.initializeQueues(CapacityScheduler.java:255) at org.apache.hadoop.yarn.server.resourcemanager.scheduler.capacity.CapacityScheduler.reinitialize(CapacityScheduler.java:220) at org.apache.hadoop.yarn.server.resourcemanager.ResourceManager.init(ResourceManager.java:226) at org.apache.hadoop.yarn.server.resourcemanager.ResourceManager.main(ResourceManager.java:710) And then this on shutdown: 13/02/08 16:00:31 INFO service.CompositeService: Error stopping ResourceManager java.lang.NullPointerException at org.apache.hadoop.yarn.server.resourcemanager.ResourceManager.stop(ResourceManager.java:590) at org.apache.hadoop.yarn.service.CompositeService$CompositeServiceShutdownHook.run(CompositeService.java:122) at org.apache.hadoop.util.ShutdownHookManager$1.run(ShutdownHookManager.java:54) Presumably this is because I don't have the CapacityScheduler queues configured at all, and the default scheduler is now the CapacityScheduler. To work around this for my testing, I switched to the FairScheduler and the RM came up just fine. -- Aaron T.
