Description
From https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1666/console :
Tests run: 14, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 63.12 sec <<< FAILURE! - in org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator testCompletedTasksRecalculateSchedule(org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator) Time elapsed: 2.083 sec <<< ERROR! org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.lang.NullPointerException at org.apache.hadoop.yarn.server.resourcemanager.scheduler.AbstractYarnScheduler.getTransferredContainers(AbstractYarnScheduler.java:50) at org.apache.hadoop.yarn.server.resourcemanager.ApplicationMasterService.registerApplicationMaster(ApplicationMasterService.java:277) at org.apache.hadoop.mapreduce.v2.app.rm.RMCommunicator.register(RMCommunicator.java:154) at org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator$MyContainerAllocator.register(TestRMContainerAllocator.java:1476) at org.apache.hadoop.mapreduce.v2.app.rm.RMCommunicator.serviceStart(RMCommunicator.java:112) at org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator.serviceStart(RMContainerAllocator.java:219) at org.apache.hadoop.service.AbstractService.start(AbstractService.java:193) at org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator$MyContainerAllocator.<init>(TestRMContainerAllocator.java:1444) at org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator$RecalculateContainerAllocator.<init>(TestRMContainerAllocator.java:1629) at org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator.testCompletedTasksRecalculateSchedule(TestRMContainerAllocator.java:1665)
In above case getMasterContainer() returned null.
AbstractYarnScheduler#getTransferredContainers() should check such condition.
