Omkar Vinit Joshi resolved YARN-541.
------------------------------------
Resolution: Invalid
> getAllocatedContainers() is not returning all the allocated containers
> ----------------------------------------------------------------------
>
> Key: YARN-541
> URL: https://issues.apache.org/jira/browse/YARN-541
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.0.3-alpha
> Environment: Redhat Linux 64-bit
> Reporter: Krishna Kishore Bonagiri
> Assignee: Omkar Vinit Joshi
> Attachments: AppMaster.stdout, yarn-dsadm-nodemanager-isredeng.out,
> yarn-dsadm-resourcemanager-isredeng.out
>
>
> 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.
> Thanks,
