Hi all I'm using apache hadoop 2.2.0 with yarn. When running mapreduce job, there are some ERROR log in ApplicationMaster:
2014-12-09 02:31:46,185 ERROR [RMCommunicator Allocator] org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator: Container complete event for unknown container id container_1417821600604_30187_01_000399 Seems that ResourceManager give more containers to ApplicationMaster than it actually need. For example, there are only 5 map and 5 reduce, need 10 containers. But ResourceManager allocate 15 containers, so there will be 5 ERROR log. Is this a bug? Can't find a jira for this. Can anyone help?
