Hi, I am running an application that had been 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, it could allocate that container. I am running only one application at a time, but 1000s of them one after another.
Is this problem seen by anyone else? I have seen that there are significant number of changes in the way ApplicationMaster.java is written now for the Distributed Shell example. There is now AMRMClient instead of AMRMProtocol. There is method addContainerRequest() which is not there earlier, and there is ConatainerRequest class now which was ResourceRequest earlier, etc. Is it adivsable to re-write my application in a similar way? Thanks, Kishore
