-----------------------------------------------

Hi Hudson & Hitesh,

  Does this mean this issue is fixed? Do you guys expect reproduce the
issue still and give you logs? I am sorry for the delay, I have been busy
with other things at work.

Thanks,
Kishore

> I am running an application that was written and working well with the hadoop-2.0.0-alpha but when I am running the same against 2.0.3-alpha, the getAllocatedContainers() method called on AMResponse is not returning all the containers allocated sometimes. For example, I request for 10 containers and this method gives me only 9 containers sometimes, and when I looked at the log of Resource Manager, the 10th container is also allocated. It happens only sometimes randomly and works fine all other times. If I send one more request for the remaining container to RM after it failed to give them the first time(and before releasing already acquired ones), it could allocate that container. I am running only one application at a time, but 1000s of them one after another.
> My main worry is, even though the RM's log is saying that all 10 requested containers are allocated,  the getAllocatedContainers() method is not returning me all of them, it returned only 9 surprisingly. I never saw this kind of issue in the previous version, i.e. hadoop-2.0.0-alpha.
