a bug in MRAppMaster?

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?

Hey, there are several issues which may cause this error. If you could
attached the full RM/NM/AppMaster logs, that will be easier for us to do
the debug.


Thanks
